i voted sbs,it just looks best with the 18 swinging arm but i will be fitting gps on my 18 im building because im fitting a 21 swinging arm.i think the best looking is the staggered look but only with a swinging arm that looks like the one on Sito Pons 1988 nsr(it looks better than the 28 rear).So Matt fancy make me a swinging arm(1988 gp nsr look) and some staggered pipes?
