Replying to Spinning vs flipping

So I'm really new to skiing, this Is my first year ever and so far I can do a decent amount of tricks 1s, 3s, just learned 5s, front swap, surface swap, 270 out, blind 270 out, switch on, some grabs etc. anyways, the other day I was at a trampoline park and learned cork 720s and I noticed that cork 7s feel easier to throw than an actual 720 or atleast it felt like it, and this got me thinking. Now Ik a cork isn't techinically a flip but is flipping things easier than spinning? Because ik some skiers that are really good at doing flip tricks like rodeos, corks, and what not but they still haven't seemed to fully master the art of spinning. Or do I have it completely wrong? And spinning 5s 7s 9s etc are easier than flipping. And another quick question off topic is that I just learned 5s and was stomping them on Wednesday but yesterday I tried them and wasn't really feeling hyped to ski, like I was just sort of out of it because I was kind of feeling tired after skiing a lot of glade runs which I usually never do because I'm always in the park and anyways I just wasn't spinning quick enough like my pop felt weak and I'm feeling worried that I couldnt get my 5s, should I be?
