I think that's a good idea. When I was learning I wasted some time trying other boards thinking that they would make me surf better when I really just should have stuck with what I was comfortable on. You'll know when you're ready to drop down in size, it just takes some time and patience. I think for your experience level and size a 6'4" is pretty solid. Have fun out there man!

It does taking getting youst to, but worth dealing with the growing pains. I will only breakout my 6'4" when swell is huge. I am 5'9" 170lbs, you being 6' I would recommend getting a 6' or 6'2" with a little more width then your 6'4".
