I have used the Matrix on my bows for 3 years now and I like them a lot. I especially like the ease of adjustment without tools. I have the .29 pins, and would not go to thinner pins myself. I do not find the pins to obstruct my target, and because of the tough terrain I usually hunt in I would be afraid of breaking thin pins on branches and such.Ibent a .29 pin carrying my bow through the cypress swamp last year and had to replace it. Replacement parts are easy to get, relatively cheap and their customer service people were a pleasure to deal with.
