we used the harpoon,we sat in the crows nest 25' above the water. All the pro's used Bosh and Lomb as their primary glasses, their backups were always the Fujion's. The bosh's cost 2200bux then and the fujion's about 450.
The key was separation of the fin from the dark of the water.
Still have my Fujion's made me a hansome during the season. Hanging out at Catalina Island was not too bad either.
