Replying to Lizzies or scratch bc or mothership flight

i Can proform the Lizzies and scratch bc and there is a 172 mo ship flight that is like 150 dollars, i was wondering which will be the best for what im going to be using them for. I Have a ski that is pure park and this ski would be dedicated to mostly all-mountain/pow/cliffs it will be used mainly at mammoth so it will probably see some park but most likely no rails. i will be able to get these  for free though since my mom said she will get them for me for xmas, so what do u think i shoud get, im mainly looking between the lizzie and scratch bc
