A lot of people who aren't highly specialized in one discipline or another carry both an RW suit and an FF one. That way they are open for all kinds of fun skydiving!
Especially if you're a slow faller you'll soon find that you'll need a tight RW suit to keep up with your friends when doing belly formations.
But suits are of course quite expensive, and as a fresh turkey money is more often than not something that you don't have too much of, so try finding used suits! They can often be modified quite easily to fit ok, and when you've found out what kind of jumping you wanna do you can order a brand new. :)
