Renfro,
Well, we don't have any fancy tests or robots or anything, but I can tell you this. Our original shafts tested to beat the original 314, and were so close to the 314-2 that it's hard to tell the difference, and the Classic is the same.
I usually play with an OB-2, and have been going back and forth between it and the Classic Pro for months. I can't tell the slightest difference in deflection or squirt. The spin is a little different as I feel I get a little easier spin with the OB-2, but maybe a little better control with the Classic Pro.
Remember, it's the effective Tip End Mass that makes the difference, not the total shaft weight.
Our non insert shafts, like the Radial we sent to Tate, are running just under 4 ounces, while the inserted models run about 4.1 to 4.2 ounces.
I hope that answers your questions!

Royce,
The smaller tip places differently on the cue ball - that's why it feels like you're getting more spin. There is an adjustment period. Once you're used to the larger tip placement, the spin arrives equally well.
Basically, it all depends on what you are used to. Changing tip diameter defintely takes an adjustment period.
