I have spoken in the past to Kim about why he designed the rifle with a 2 1/2 inch clamp. The rifles is meassured for stiffness from the butt. The butt is where you will hold the club so that's where he designed it from. A blank rifle shaft has a uniflex reinforced tip. It plays stiiffer because there is not much flex going on from the point the tip reinforcement starts down to the tip. The middle of the shaft provides the flexing area of the shaft. It is this feature that allowed the Rifle to be flighted. It was this reason that the blank parralell tip shafts are sold in very tight frequency tolerance sets. The reinforced tip is also why they are pretty accurate when tipping them. By putting more material in the butt as you go up in stiffness the lower end of the shaft flex stays the same.
The biggest mistake you made was using taper tips. It doesn't matter what brand you use of tapper tips they almost never work out to what you want.

As I recall, Rifles were clamped at 2 1/2" with a really heavy tip weight attached. Virtually all their shafts freq'd and played much stiffer than advertised. I recall using 4.0's to simulate 5" clamped "R" flexes. I never could figure out the rationale for 2 1/2" clamps and a heavy weight.
