Weird. I have a set of Sugoi RSE and they're my least favorite set of bibs and I find them loose compared to my Giordanos and Castellis (looser than PI Pro as well). I used to think they were OK but I changed saddles last month and now I really don't like them. The legs are shorter than I like too.
Castelli body paint slot right after Castelli free race aero in my preferred bibs - the shoulder straps are sort of plasticized and not as comfortable as cloth ones IMO.
I agree with merlin though - if you found something you like, there's no reason not to stick with it.
