Hey Lacey,
I used a coiled leggie in the surf and I hated it. Like Cammo said it lost it's shape and after a
good stretch it would bunch up and tie itself in knots. Then all of a sudden I had a 2' leggie
instead of the original 8'.
Also if you're surfing beachies with any weed in the water the coil catches the weed, not
usually while surfing but more when you come off near the shore/weed. At Southside mine got
caught in kelp and I had to take a few on the head trying to free it.
I've gone the heavy duty 6' and 7' leggies and it has really limited the problem. On an 8'6"
board (pointy nose) a 6' leash is plenty.
Thats my experience anyway...
