Yep bodyboard fin saver straps. The water comes up the leg not the other way.
Fall over and water goes down the neck, ends up in the legs too. And you'll still get spray blasting up the legs, even with straps on tight.
Straps plus holes are the ticket to almost completely elimanating elephant legs.
Fine soldering iron tip, from the inside out - you want to just get the tip to poke through the outside. A tiny hole is all you need, and the heat will qauterize the suit... About an inch above where the steals would be, in the middle at the back.
I'm going to try heating up a needle and seeing if a hole that small will work too.
