Weso, trim is the best way to go! Even if you aren't trying to flip, getting through breakers is a lot easier when you can pop the nose up with the trim, rather than having to work the bars. Nozzle depends on your budget IMO, you could make a systems using a raider trim ring for cheap, the X-metal system is about $400+ but it wont survive a hit on the rear end as the SS trim ring will bend (from experience), the Thrust system is really nice, I ran one for a few years before it gave out, I think those are $700+.
Like Bruce said, some decent surf, hit the wave late and commit to it, if you are half way there already a trim system will most likely give you the extra rotation!
Good luck!
