I don't know if anyone else has found this, but I find that walk designer loops don't work well with dynamics.

There's a couple of reasons for this: Firstly most of the walks seem to contain sudden, unnatural, accelerations - paticularly of the thighs - that cause poke through which is very difficult to spot in Poser previews. Second the hair and cloth are simply not in the correct position in the last frame to realistically blend back into the first.
