Yeah I used it as my only board for about 6 months. Handles everything but dredging barrels. That said my mate took his 510 to France and said he surfed 5-6ft La Graviere on it and it went well. Not sure I'd try that though.
A touch more nose rocker helps, as well as the narrower nose. Nice bit of tail rocker and thinners rail too so you can jam it into a steeper section easier.
Another option is to hold out for the mini driver.
