I like the idea of this, but I've got very serious questions about the longevity of this setup with a bigger, or more dynamic rider on it... that L is not nearly as strong as I'd like, I'm curious how long it will hold up. (I already have to re-rivet my boards every season and a 1/2 or so)
These are my reservations also. I used thicker material for the everything for this reason. The L isn't the only thing holding it together. The main piece is made from the same thickness stock and with it being a U-shape has quite a bit of strength on it's own. The outside rail might be an issue at some point and I'll deal with it then.
I'm about 195 fully loaded and don't do a lot of jumping if that helps set the stage. I like being able to get that much farther forward and the freedom from not having a toe box is great. I'm a dirt biker so moving my feet around is natural.
