CRG KT2/4 for 2021

For 2021, CRG released a new CRG KT2/4 chassis, which is basically the KT4 with all round 30mm tubing. I have heard a lot of drivers praising this frame for TAG classes (mainly mentioning that it has a better turn in than the KT2), and have also heard some rumors that most of the drivers from the official team are running it instead of the KT2. Has anyone here had the opportunity to drive it?

More information can be found in the press release here.

Any updates on these karts my local dealer on wants to sell me the kt4 over the kt2
