Isospeed Grey Fire Official Thread.

Guys, I require some assistance. I have a reel of 1.30mm gauge Grey Fire - I’m really into it and I do genuinely like it. I’m a prolific string breaker usually but this stuff seems pretty indestructible. I must have got 15-20 hours out of it at least, it is going thin in places now (just off centre in hitting zone) but it just doesn’t seem to want to pop.

It’s lovely when freshly re-strung but as it wears I’m less of a fan. I have a hard time kicking my second serve in which I’ve never had problems with before. My topspin forehand and single handed backhand are fine but lack a bit of a bit of oomph as the string becomes played in.

What would a sublime combination be with this string, I want durability as well as playability? Do I put the Grey Fire in the crosses or mains and do I drop my tension (normally do 56lbs).

P.S. I am a returner to tennis and had experience of Big Banger when I was a junior but the last 2 years I’ve been playing multis so I’m quite new to the poly world.

Many thanks!!

I've put rpm in the mains, or as jolly said black Knight. Also no poly plays well after 8 hours. This one is above average though

whats so special about a round grey string? There are millions of it and a lot of them much cheaper too than the advised price of 180euro. I suspect some reviewers are not that unbiassed, lol

Which country are you trying to purchase from?
Thanks for spotting my post! Basically, I’ve looked on Stringers World (I’m from England) but they are out of stock. I don’t know of any other UK based retailers who can sell me a reel. I obviously can use your European website but I need the reel fairly imminently and presumably it’ll take up to a 5-7 days?

P.S. What would you recommend to compliment Isospeed Grey Fire 1.30mm, mains/crosses and what tension? I’m used to multis at 56lbs, I hit with a lot of spin off both wings and I’m currently converting to the poly/co-poly world!

Just try it on its own
I use Rpm blast in the mains. Lovely combo, feels crisp and soft with access to spin. Lasts a bit longer with the grey fire too
 
Tried some Jolly-inspired setups with Grey Fire.

The BK/GF hybrid is legit and produces a metric ****ton of spin. Hits a big ball. I found it a little harsh, and I couldn't get my serve dialed in for the life of me. Likely more my fault than the string's.

I really dig GF in a full bed though. Lots of pocketing, good spin for a round string, also hits a big ball. Bit more zip than I'm used to. Going to see how it settles and lasts, but it's the first string in a while that has a chance of tempting me away from Razor Code.

Both strung around 49# in a leaded up Ezone 98.

FYI BK is harsh in the beginning and gets better as you play it. I don't understand how.

Give it some time.

Also the blend needs to be strung pretty loose.

Piling on here to make the point ...

All poly should be cut out by the 12 hour mark (unless you are just batting the ball around coaching or something).

Unlike all the strings that came before it, poly is generally shot way before it breaks unless you go with a real light gauge (which makes a good case for trying out a thin gauge; some people love 1.15 mm and below).

Best part about grey fire either in the BK hybrid or full bed is the very loud and clear "crack" sound it makes like a whip when you hit the ball! Very satisfying from a sensory perspective. When you hit the ball hard, it really feels like you are hitting the ball hard and are rewarded for it.

You should try Rexxxer!

Black Fire is stiffer, total control string, needs lower tension. Kind of like stiffer Head Hawk, comparable to 4G and Poly Tour Strike, but different of course. Can give you an injury, just like 4G and PTS. More of an old school stiff poly for old school heavy flexy frames.
