same boat. the OG profile II was very similar in design to the CCM cage but the large in that was akin to perhaps an "extra Medium" of a 580. I also found w/ the CCM, that if I moved the J clips up higher, the fit was better - but was only a minor remedy. The Large CCM was just big lobster trap. The newer Profile II isn't "shaped as cool" as the first iteration, but I still prefer that as my favorite cage. Either one will do.
