We did this IM set LCM. It got a little hairy/confusing in the second round when we went 200 to 50 instead of 50 to 200.
The 50s in between were best non-free (for non-IMers) or worst non-free (for IMers). The IMers were thus working on their weakness. Being able to go best stroke allowed the non-IMers to make the set a little more relevant for them.
