I've been thru a lot of LFT tomos (vanguards/vaders) for kiting (normal surf construction - not kite construction), only once has one snapped on me and that was in the surf while prone surfing 3-4ft. It may have already had some stress fractures on the rails from kiting jumps.. not sure.
I usually buy them S/H keep them for 6-12 months and move them on as they get too much foot depression (apparently normal for LFT), but I worry that they will eventually break. Its the only board that is small enough for kiting and can be used for surfing also.
Picking up a Chumlee on special soon to replace timbertek baked potato, its unbelieveably light, so hope its as strong as they say, too good to use it for kiting though
