    Check out the video of Patrice Kuchna, known as the Human Machine, as he conducts string durability testing for Tecnifibre:

    http://www.tennis-warehouse.com/vlogpageFO.html?ccode=THEMACHINE

    This guy breaks gut in about 60 hits. Most multis break after about 100-120 hits. Tecnifibre NRG2 17 lasted over 160 hits. A poly lasts about 220 hits.

    wait so does NRG 16 last longer or the X-One Biphase 16? and do X-One Biphase Red feel any different from the natural color version?

    Hey Chris....

    Would you mind to post the specs of the racquet used by
    "The Human Machine"????



    Thanks....

    What's amazing is that he can even find the strings on his forehand, given that he pulls his head up on each and every shot, let alone hit with any consistency.

    Not only that, but his wear pattern is extremely tight. He hits both his forehand and backhand in the same part of the stringbed so the string takes a beating on both sides. He always breaks either the 3rd, 4th or 5th main string and hits high up in the stringbed. The rest of the stringbed is untouched with no ball fuzz evident at all. Just a really tight wear pattern all in one location.

    The racquet used looked like a Wilson Hyper Hammer 2.3 or something. He has a stack of them so he can have sets of 4-5 racquets with the same string. The most amazing thing is he can test one string, then test two others, then come back to the first string some 40 minutes later and it will break within 5-10 hits of the first batch - that's how consistent he is.

    Blew my mind watching this guy.

    Chris, TW.

    holy cow that is machine like; truly amazing to hit with that level of consistency everytime he tests a new set.

    No offence to anyone but this is what i call a TRUE Playtester. Some people claim to playtest alot of strings but do they have the right techniques/skills and resources?? :confused:

    With such racquet, I can brake the strings even faster.

    I would like to see him test sensation on that racquet. I would guess 30 hits tops.

    Have they changed the composition of NRG2 over the last few years? I ask this because durability was never a forte of this string when I used to play it and I think it was said it took him longer to break NRG2 than some of the other strings I thought were more durable? sweet playing string..just not very rugged. or did i get this wrong?

    Also, I think the guys' head movement was more just a quirk in his technique rather than a flaw...i mean his head wasnt spinning around like from the Exorcist a la the Roddick forehand, and each forehand was obviously the same as the last...the guy was obviously a great hitter, but did have a bit of a hitch in his get along ;)

    As far as the tight wear pattern, other than his consistency, that would be because his racquets evidently have an up and down side to them. also most better players hit it a bit high in the stringbed, so that's pretty normal I think. Not being of this guys caliber, I break strings in the same place too and my frames have an up and down side..when they fray off to the one side by 3 mains or so, i replace the overgrip with a new one wrapped starting from the opposite side so my racquet has the other end as 'up' and proceed to wear out that new part of the stringbed..i get a lot more mileage out of my gut hybrids that way...this may work for some others

    No offense taken. What I've found most people look for in a play test is how a piece of equipment holds up in the " real world" of the general user. He is a durability tester for the company. Not once did I notice that anything was said about control, spin production or my favorite feel.

    I'm pretty sure you heard correctly. The problem was we don't know what he compared it to. So is 160 hits really good for a multi, or was that just good for the set of 3 or 4 he tested. Also 220 hits for a poly? We don't know what the poly was either. I've played some polys that don't last as long as some multis. Everything is relative. He was using a very open pattern frame, so I would guess that primarily he was testing the abrasion resistance of the string. Also since he did this in one session, you would presume that a string with a lubricant on it, like NRG2 would fare better than one without. However, in normal conditions over time, the lubricant might wear off after several days or a week of hitting, and the abrasion resistance might be much worse without the lubricant, and the string might break faster than a string that never had a lubricant on it to start with. I would say that the testing he was doing is much more useful for the lab guys working on string construction than it would be for a typical player. But we don't really know either way since we don't have much data to work with.

    I don't think thats necessarily true. Some players do keep track of how many hours they get out of a certain string. Or how many weeks they typically play with a certain string before it breaks. Factor in the cost and there ya go.

    I was speaking of the data from the "machine" who was the subject of this thread. Obviously if you collect your own data, or someone gives you their data then you have some data to work with. What we don't have is much data from this guy. Just a few data points and only one specific string reference that I recall.

    That is one of the largest racquet heads I've ever seen. Reminded me of the Big Bubba. ;o)

    Did anyone else notice that the Machine seems to open up a bit too much on his bh? ;o)

    I wasn't so much impressed by his strokes as I was by his fitness and the size of the freakin' racquet. It almost looks like one of those big ass display racquets they have in the stores.

    I cannot play this video, due to some missing quicktime component not found on the quicktime server. Can this video be reposted as windows media or something, like the newer vlogs are?

    Man! What a beast! I don't think some of the guys listened to the explanation of why he uses that big*ss racquet. It accelerates the string breaking. I can't believe the spin he was putting on the ball and his consistency on every shot. Same motion and everything. Awesome to watch. Thanks Chris. :)

    He doesnt even look at the ball when he hits it.

    I would of thought he has more chance breaking his frame than the strings

    I wonder if anyone recorded how the hitting partner of the human machine did. How often he breaks HIS strings etc. He must be very consistent too. Or was it a ball machine? I am yet to watch the video.

    Damn. That guy's amazing. My arm hurts just watching it - I can't quite get over the fact that you don't get to see if those shots are going in on the other side - but his stamina is incredible! :shock: In the U.S. he might have gotten crap for his name (Patrice) just up until the point someone saw him hitting like that! :) I also think its very smart and cool to see that this guy found a way to continue his tennis career outside the big tours without having to just teach at a club somewhere (which he said he does too). I wish that there were more things like this during televised tennis matches - like on the PGA tour. Super cool.

    Probably a dumb question but what stopped this guy from becoming big on the ATP? Conditioning maybe?

    We must remember that he was born in 1963! All of us should hope we look and play as well as he does when we are 45!! Despite the static ball feeds from his Father, I just hope I can hit half as hard when I am that old. :?

    Great post.

    Umm, the video won't work. Any help? It's just stuck on the Quicktime logo and won't play.
