71/4 How Strong Really

Yikes....I knew they were weak, won't be making any passes with these kind of odds, the track is almost 90 miles away and I don't think wife would be amused if we had to hitch a ride home and pay a large tow bill. I have a 81/4 bbp but it needs every thing...I have heard these are much stronger...I think I will just spend the money on it and then try it. Thanks for all the info.
