Say a frame comes in two sizes that have almost the same reach (within a few mm), but different stack numbers. Size A is smaller, the seat post would have to be longer, and there would have to be ~2cm of spacers on the steerer underneath the stem. Size B is larger, the stem would be essentially slammed, the seat post would obviously poke out less.
Any specific reasons to prefer frame A or B? B sounds more 'appropriately' sized. A will be a little bit lighter probably... any other relevant differences?
