The rest that is being displayed is a QAD Drop Away Rest and the video is of a prototype that was made by Frank, from Archery Unlimited, Inc. They are located in Grand Rapids, Michigan and can be reached at 866-670-8511. or firstname.lastname@example.org
Frank has not started production of any of these rest yet. He's planning on producing a few by hand with his CAD Machine, but they will be somewhat expensive, since the base QAD rest sells for $130. and then the set up to do the machined bracket to adapt it to the TAC15's 8is about 4 hours of labor. Then the bracket must be sent out to anodize it for rust proofing, so you can imagine what the approximate price might be.
The minute you decide to go to this type of a rest, you'll also need to shorten your Weaver Style Rail so a 3 fletch will slide back to the fully cocked position. If you look closely at the video, you'll notice he modified his TAC15 to allow for this.
Although I like the idea of using a drop away rest, since all my competition compound bows are set with them, I won't adapt one to my TAC15i because it's way to much money and to little performance gained.
I'm not a fan of the Whisker Biscuit because I don't like anything making contact with my arrows as they pass over or through a rest. I also don't like the fact that the biscuits wear over time and they're also affected by temperature changes. I'm not sure if you've ever seen what happens when it gets really cold and your Whisker Biscuit freezes?
At $130 dollars for a good drop away rest, that's not to unreasonable, but if I have to pay double that for a rest, then the cost just became out of hand for my tastes.
I told Frank, I'm willing to test and evaluate his units in a couple of months and then produce some pre-release articles for him, but I have no interest in changing to or using these rests if I would need to refletch all my arrows to 3 fletch configurations. I'm well tuned with what I have, so it's not providing any significant benefits to me.
I watched the video and noted a couple things. One was the fact that they claim they're shooting about 50 meter, yet if you watch him adjust his HHA Optimizer Speed Dial, he's clearly using a 20 yard setting. His accuracy at 20 yards is absolutely terrible. I can shoot out the X's on a 1.5" florescent dot at 50 yards all day long with my TAC15i, so he needs to do some serious tuning from what I can see.
He states that he's using 160 grain points on his arrows. We know from testing and experience that the more weight you add to the TAC15 Arrows, the flight anomalies develop and PSE's engineers have confirmed this. That's why they recommend broadheads that do not exceed 100 grains.
When I spoke to Frank, he stated that between the silencing materials he has applied and his arrows being over 600 grains, his velocity is about 350 fps. No problem with that as long as he's not attempting any long range shots at 80 to 100 yards.
