I have several of the new take downs, some older ones two. I don't know if you have played around with one of the new ones yet but I absolutely love the grip. I have a couple of the diamondwood ones,a bubinga and the newer gray actionwood. Plan on picking up one of the two tone risers as well.
I am currently hunting with one of the 2011 black diamondwood "A" risers and #3 limbs. I don't see how you could get the arrow to lay closer to your hand without it actually resting on it. That being said. It is obvious that the final finishing of the grips is done by hand, and by different guys. I have seen some of the grips that are narrower than others and shelfs that are higher.
