Yeah, vert is kinda gimped. I love mine, but no PTM and no underbelly really annoys me.
What they ^ said about traction, except this: If you are used to driving rear wheel hp, turn off all the nannies. If you kick the rear out and try to correct yourself while the stabilitrack is also trying to correct, things get really weird, and dangerous. If using Stabilitrack remember this : release gas+steer. Almost got me killed learning that.
