Well, I have learned stunts I couldn't do before, like grinding and stuff, and yeah I also noticed the nrg500 is good, I couldn't get on the billboards in the skatepark without it. thanks for the tips!
Edit: btw. I'm about to make a new stunt movie, I know it'll be better, I think I'll do this one on SA-MP
Oh and if you wanna find me on SA-MP I'm probably on the modes, SA-STUNT or the gta tournament servers
