There have been a couple of U.S. men that have competed the full twisting double front on floor, but I don’t remember how successful their attempts were. Sean Golden was the first, around 2004-2005, and Bobby Baker was the second. Here is one of his attempts in warm-up from a Winter Cup in 2013/2014.
As a kid in trampoline, I started my routine with a full in half out. I would feel more comfortable doing a full in full out than a full in front. It feels much more like one fluid motion where you still can spot the ground to land versus doing a full and then trying to find the front tuck.
