my vote is for the stadium for sure. even now i did much better with it than a used legend.
stadium will last 2-3x as long as the legend as well.
it's so tough to know for sure until you try it though. i really liked the legend the first time i hit with it, but quickly grew out of that phase when i stopped hitting evil BP's with it.
neither bat is a dud, but when i measured my BBS with a radar, a low hit stadium did better than a used legend for me. i'd put them on relatively equal ground when it came to performance, since i liked the feel of the stadium better, i hit better with it, and with the superior durability on top of that, there was no reason to keep the legend, which i did sell.
my 2cents on the feel. both were the 12inch barrel, so very natural for me(being used to the juggy) and i didn't find it too hard to hit the sweet spot with either. the legend swung pretty heavy and felt really soft without being responsive. it just felt like i was hitting mush almost no matter what ball we hit. pretty much only the evil BP's felt good with it. gold dots, grey dots, hot dots, dudley thunder heats being the others. the stadium felt stiff, about the stiffest bat i've swung and actually liked. didn't feel too endloaded because they seem to swing under or right at sticker. if they weren't going to be illegal for me to use next year, i would have kept the stadium on had on loan for sure. it was doing well with about 200hits on it, would have been nice to get a lot more and see where it ended up
