all the first gears are the same but its the second gears that are different... so basically you will always have the same jump off of the line, but changing the gears sets to get you a different second gear ratio will change your top end speed...
if you are just bashing, any one of them will do, i just suggest that you change your cb and spur combo...
i am running the wide ratio with a 17CB and 36 tooth spur... in high traction situations it will wheelie and i still have plenty of spunk off the line, but it still pulls really hard on the top end with plenty of speed for those longer jumps and straights
