Getting to the next stage...

Hi All,
I'm riding a 9'2 epoxy longboard on an East Coast (NY, USA) beachbreak usually about thigh to stomach high. I'm a 70kg(160lbs) advanced beginner (catching 75% of what I go for, popping with few problems and heading down the line) and stoked, but I'm looking to step-up my skills (turns and noseriding!). My board is a 2+1 with an 8" center fin and I've been interested in riding it as a single to learn the tradition but here's my question: As far as progressing is concerned am I better off sticking with the 2+1 set-up or should I go to the single fin (I planned on using the 8" fin and putting it all the way back in the box). There's so many variables- turning vs. noseriding vs. drag vs. appropriate conditions, etc. that I don't feel like I have the experience or wisdom to make the best choice for myself! Any recommendations? Thanks!
