Larry,
Got to thinking about what I put in last post and thought I would clarify it further. I originally got the 314 to use with my Whistler full splice, but have ended up using the original shafts, which have ivory ferrules and moori tips. Have rolled both of my Scruggs shafts, both of my Whistler shafts, and a predator 314-2 shaft that I have on a 5K2, and all have a very slight change in the amount of daylight that shows under the shaft when you get down level with it and roll it on the table. There is no perceivable lift of the shaft that can be discerned when rolled. I attribute any change in the amount of light seen when shaft is rolled to the professional taper that is on all my shafts.
Like said before, I have ended up using the original shafts for my Whistler and this 314 rarely ever leaves the case, so when saw your post, thought it might be of use rather than sitting in the case.
