I was wondering if I could make a combo with v2 using gravity reboot is it a little competitive?
What recommended drivers should I use

V2 is just too light to be competitive anymore. Gravity is outclassed by the new Core Disks and Frames and Reboot is just NO

V3.6M.Hn is good for attack

I could test it, but I would have to make a mix of Hasbro and TT.
