My experience with the MU figures is that they come apart easier than the Joes.

As for opening the Joe torsos, i have found that using the exacto blade and cutting the seam under the arms helps to open the torso without too much visible damage to the torso. I use the blade and run it along the seam repeatedly till i get down in between the 2 halves. Then i use the smallest jeweler's screwdriver (flat head) and push it in between the pieces (starting at the bottom and working up the armpits on each side) by the time i get to the top the torso 'pops' open allowing me to keep the pegs that hold the torso together in the shoulders.

As for the arm swaps. The arms swap back nd forth like champs.
