As a ref it would be a very very useful thing, the problem is you would have to get all organisers to agree to use this new trigger. Now unless you were paying them I cant see them going for it as they are restricting players to what they use and making you a lot of money.
I dont go on the chrono very often as I am normally a field ultimate but when I do, im not totally looking for trigger bounce. So what if your gat adds a couple of shots when its shooting. As long as I cant get it to go full auto etc trigger bounce doesnt bother me. Are you really in a game going to be looking for a sweatspot on a trigger to get a couple of extra bps and not paying attention to the game. Or you could be the bloke whos just hit you as he is concentrating and not looking for a sweetspot.
to be truthful I wouldnt buy one for toffee. If you get your marker to bounce past any chrono judge all the better.
