I guess its always a trade off, less weight on the bottom end will equate to less strength. Interestingly my speedy engine rods are the same and each has significantly stretched at the little end hole. so much so that I have had to retire them.
I wonder if it is the other end of the rod that is the weak link rather than the big end. Have others had the same issue?
