There's a huge difference between your 52 cm Drake and f.ex. 59 cm freeride/-race fins, been there done that.
I have now in my 155 go both 52 Drake and 59 cm Tekknosport and with my 9.0 Gator there's only one option. The Drake tends to spin out a lot easier and there's simply not enough vertical (??) resistance in it. Upwind performace in also from another planet.
Go for bigger, it pays!
