Dont automatically asume as you a big bastard you wont fit in a "normal" size seat, as its how big your hips are rather than the rest of you.
I fit in fucking tiny seats that people nowhere near as big as me cant get in, so always try one out before you go for the biggun, as a big seat that doesnt hold you in tight is just useless and ends up more uncomfortable in the first place.
