Repeated this set again today, minus the tossed salad IM at the end. I reached the HTFU point and cut the workout short today, only doing 2 rounds instead of 4.
I finished the workout with about 10-12 x 25 of fly drills from body dolphin to catch, to exit to single arm, then butter frog and finally full stroke fly. Felt awesome by the end. Nothign like a good length of butterfly to make you happy.
