I have a small rack of these things, all the older style that arent colored, except for the 4.5, and that one doesnt get used because of its awkwardness, the other 3 i have are 2.5 and 2 # 3`s, those ones are perfect, the cam lobes dont over rotate in cracks, are totaly bomber/trustworthy...i get a little worried about the little one walking around in a crack and getting stuck sometimes but i would fall on it just the same....all these pieces, i have traded for, with wallrats from the valley, there must be a reason they always have them...
stay away from the biggest sizes, and anything smaller than the 2.5
