Native, I deleted Sasquatch for a reason. That is because upon reflection I did not think it right to speak for another bowyer, even my best friend.
To answer your question about the static tips , there are at least two ways and a combination of the two to make any limb a static. you can do it by geometry, by tip wedge , wood, glass , or carbon. or a combination of geometry and wedge/
I suspect that the gentleman that brought this into the conversation is saying that the static is created by geometry. In a D and R limb that would actually make the bow limb a semi static as the tip will eventually bend toward the very end of the draw/ This is true even of a super radical reflex. The only way to make it a true static tip would be to use the combination.
As to whether it improves performance , That would depend entirely on the bowyer and the balance of the entire bow design. If it were just as simple as throwing in tip wedges and making sharp bends in the limb then everyone would do it. To get it performing right takes a lot of r and d and a lot of time and money. Once a bowyer gets that done he kind of tends to keep the results to himself.
God bless and hope this helps. Steve
