Nasser, like a lot of today's gh guys, has too wide and big a torso in relation to the arms. Doesn't look as good; arms haven't grown as much over the last 3 decades, in relation to torsos.
I think the front double bi shot is a lot more than just how good your arms or bi's are...so I'd say the guy with the big and wide torso has a better chance of beating the guy with the regulary torso in the pose.
That's in general, in Nasser's case I dont think his arms are too small for his torso, check it out this in pic (notice I take any excuse to post a nasser pic) lol
