I'd stick with the small frame if the reach feels right. I have a 32.5" cycling inseam and ride a 15" rigid 26er with 400mm seatpost.
I always go for the reach. I know I want something with around a 56cm reach. I've got that 15" and my 18" Trek 400 that measure 56cm reach. I've had 17" and 17.5" frames in there too.
