Finally got to hit with mine last night - for context, I've got the PSC, K95, BLX in my bag, K95 was my go-to for quite a while and the 2017 reissue has been my main racket for the last couple of years. I strung it up with a hybrid of Cyclone 17 at 48lbs and Prince Duraflex at 52lbs so I could compare it with the 2017 model (I had it strung like this for quite a while), and it was a surprising playtest (in a good way) - much softer than I was expecting, and also less power than I was expecting.
I've got a leather grip on the way that I'll be putting on as soon as it arrives, it made it somewhat harder to compare to the 2017 model having the different grip on there so I'll follow up once I've got the new one on and had a hit with it, but comparing it to the K95, it is significantly softer on contact and a little less powerful, I haven't played the nCode so I can't compare to that but it's noticeably flexier than the K95. The lower power level was the most surprising thing though, I was having to give the ball a fair thump to get it to go deep, which for me personally was a good thing as I usually like to rein in the power just a touch on the Six.One and so have to string a little higher than I normally would, but I think I'll be stringing a full bed of Poly Tour Pro at 46 next time and seeing how that goes. Spin potential was good, serving was the same 'point and shoot' feel that I've had with every Six.One, and it was a little less stable than I would like but I think that has more to do with the stringing set-up than the racket itself, I'm confident a restring & a leather grip will fix that.
Overall, I'd put it up there with the Prince 93P and PT2.0 as one of the best rackets I've hit with in recent times, definitely glad I bit the bullet and got one - and in case there was any doubt, the cosmetic is absolutely sexy in person. Pictures online don't quite do it justice, it's a very cool looking bit of kit.
