We really like the Turbo Tuff I-Beam line from Manley. We have never been able to break one, even over the 1000whp mark, and they hold up well to extended abuse. They are probably the strongest rod for the money and we suggest them to anyone who wants to sleep well at night knowing they don't have to worry about their rods being a weak link in their high power build.
