yea, spent 14.5 years of my life there. Surfed Boat Basin(probably where you refered to as the Marina), Ricks reef, Talafofo, etc. Bali is outrageous. Mostly lefts for us goofy footers. Learned to fly there, first job flying the awesome aircraft made by the Shorts brothers. First waves at Boat Basin, pretty ballsie, if it is big on the lefts, whew, reef was pretty shallow...
I surfed Costa Rica once last year February, 3 to 5 feet, Oeste, Playa Hermosa, Jaco, cool but no Bali, I have a hard time not comparing everywhere to Bali, even Puerto Escondido. PE is awesome, really quiet, cool to hang out, talk with travelers, simular to Bali.
I used to Jump seat on CAL every other month to Bali from Guam. Hot women, Hot waves, hot food...!
Thanks for all the replies about the type training, just looking for a good deal. Just wanna surf.
