Sure grip 7 1/4 strenght?

I am in the process of pulling out my 7 1/4 today. It made it threw 4 years of driving with me behind the wheel and a 360 that has some goodies. I had it at the track twice and went three two sets of tires. I am not trying to contradict these guys but from my experience as long as you are not hooking up then it will be fine.
