This is a question for all you long time Mathews shooters. I picked up an older Feather Max for my wife, It came with 2 sets of limbs and cams ect. (50-60#, & 40-50#) it's got the 60# set up on it and I want change it over to 50#, my question is the chart on mathews sight shows only 1 string size and I don't think the sizes are the same since there is a big differince in cam and wheel size, I want to make sure before I order a set from the"Gibmiester" Thanks for any help..... joe
