Wonder if there is added benefit in term of stability/performance (2 screws vs 1) compared to nobile system. On Nobile it s pretty tight already with 1 screw, also has added benefit of fin poping out of board without damaging board in case you catch a shallow sandbar.
Interesting concept, but how many people actually swap out their TT fins on a regular basis? They aren't like surfboard fins. I've never even heard of anybody changing TT fins for different conditions.
It also doesn't make any sense for travel because, if you're going to pull your fins off, you need to take a screwdriver anyway to remount your bindings. Pretty silly to remove your fins but leave the straps on.
Got used Nobile board with 2 sets of fins, one small one large. I was adviced to use larger fins ocean side or in light wind. I haven't been ocean side or in chop in a while, also I don't think I would bother switching them but I see why people like that system.
When I travel I don't remove the straps, I feel like they are less likely to get damaged while staying on the board, they have to be somewhere in the bag anyway... So I don't need a screwdriver when I travel.
Leaving fins on can break the board because of centered pressure around the fin. + grinding fins and a hole through the bag.
