I have only ever tried the outer reef leggie once when sambo, dogman and i played boards swaps one day. I had to keep looking back to see if dogman had tied a big chunk of weed to it! Too much drag and over engineered.
from a previous topic....
All our 7', 9' & 11' leggies come in 2 styles, lightweight comp and heavyweight. I use the 9' heavyweight with my 14kg Bombora Chaser and it has survived multiple big wave thrashings.
A big key to leggie survival is your actions when being dragged under water.
Try and play tug-a-war with your board straightaway and you will snap a leggie or leg.
Lay back and let the board drag you until the force dissipates and then pull back it will last forever.
