I've used them for about 6 or 8 years on rattle traps. I would put a short shank mustad triple grip on the front and a spintech on the back due to losing alot of fish. After I did this I hardly ever lost a fish anymore. Another trick you can do which is cheaper is to buy some split rings and put 2 on the front and the back and this will allow the trebles to rotate a good bit but will not spin anything like the spintechs but it is a big improvement over a single split ring.
