Hey Nick- My Picasso is a 60cm, with one 20mm band. I have the extra red one on there just in case the black one breaks. This is the problem with one band guns...when the band breaks, you are SOL. I'd highly recommend this gun if you can track it down. I rarely wash any of my gear, and this gun has outlasted Riffes, Pelaj, Rob Allen, and JBL. I do like Riffes and Rob Allens very much, but love my Picasso.
