I have a Whammy and I know what you are talking about. Yes, the prongs are a new design. The guy at the pro shop told me that the new prongs were supposed to provide BETTER arrow containment than the old (07) style pongs. Perhaps you should give them a try (turn the bow to 80ish degrees to the side and see what happens) before swapping them out....
Hmmm...
I'm not an experienced archer, but as an engineer I do not buy that at all. The deep V provides a more horizontal ledge for the arrow to rest on when the bow is turned at steep angles. This newer design is like a cliff at steep angles! I just took the rest in my hand and placed an arrow on it for a makeshift test to try and get a feel for what is going on!
My thoughts were that this new design might be to minimize "side to side" resistance to the arrow as it is being fired, allowing the arrow to flex is it wants to. I do hear complaints about the WhiskerBiscuit that it is too constricting to allow the arrow to move freely. I'm guessing (keyword: guessing) that this new design is better for allowing the natural flexing of the arrow to occur without interaction from the rest, while providing the proper support against gravity, until the arrow gains sufficient velocity. I also suspect that the shallower V on this new design reduces the pressure on the arrow, and consequently, the friction, allowing for a slight increase in arrow speed.
I don't doubt that there probably isn't an advantage to the new design, but since I'm new to the sport, and don't need 1" groups at 80 yards, I'd rather have the more constraining deep V to keep my arrow on the rest! Looking at the price ranges, designs, and even the name of the company itself, I'm under the impression that Spot-Hogg is geared a little bit more toward the target archer than the hunter.
You do speak of "swapping them out." Did you have the new design and get the old prongs somewhere and swap them out? I'd really like to know where/how to get the old prongs!
