I think it just depends on what is more comfortable for you. If you want to learn the HS BS 180, then first learn it in the flats and then inside-out before you take it w2w. I got the first two steps of this but had problems taking it w2w. catching your heel edge on these as you're coming down are the worst crashes I've taken wakeboarding. Have fun!
Seriously, I think it's like everything else...WAIT to spin and you'll be fine. I've never tried the TS BS 180 but I think most would agree that it is hard to initiate and pass, but then easier to land once you have the handle.
