Might try this later but I suck at OH, also I created a thread for cubing challenges, you can get to it by searching 'cubing challenges thread' on the forums(not really active, but I want to get it active again)
I tried it, here are my results. Scrambles
3x3OH: R L2 F D2 L2 B' D2 B' D2 F' D2 L U R U2 L F' R2
Pyraminx: B L B' U' L R B L' U' r'
3x3: R2 L' D L' B R' D F L D2 L2 U2 R B2 U2 D2 L' D
2x2: U' R U2 R U R U' F2 U2
Finished OH at 25, finished Pyra at 34, finished 3x3 at 47, and ended the relay with a final time of 56.01.
This might be hard for me to be good at because I main APB and I'm not too good yet, so I will do two sets:
set 1(with APB):
2x2: R' F' U R2 U2 R' U R' U'
3x3: F2 D2 R2 D' B2 D2 F2 L2 F2 D L' U' F' D' B D L2 U B2 L'
3x3 oh: F' D2 R D F' U L F' U2 L2 B R2 U2 L2 U2 B L2 B R2 D L
pyraminx: U' B' R' U' L R' B U' l u'
Time List:
