good, i had same problem!
my views: deagles and pistols would be good to dby with (cops on bikes use pistol, homies use deagles if you've completed SP that far!)
Definately keep 360 aim (and i don't think you should disable accelerate while doing this) it's fun and balances gameplay.
...and damn! i hate it in sa-mp when someone comes and autoaim driveby's you! it should definately be disabled and never talked of again!
