non tumbling

Im so frustrated with my tumbling right now. I'm 16 now but when I was 13 I was on a J5 and S4 team and training all my level 6 skills on the rod/spotted on the floor. On my team I was a main tumbler and center flyer. My coaches started pushing me around February to get all of my level 6 skills...

Trying to find out if in L4 non tumbling I can do a spotted back tuck (all on the performing surface). It falls under stunting rules but I am unclear I whether I can have one spotter just in contact or if I need two. I certainly don’t want a hand to hand connection. Thanks in advance!
