Any idea how the new pro v1s are different than the 2011 model?

no it should not. The only thing is if you needed to with the 12 degree drives you could go up higher in degrees. But if 12 is all you need I say stick with your 10.5 

I have heard that they will be for custom order in May. 15th if i recall correctly.

Of the "stock" offerings, you may want to try the Aldila Phenom or the Mitsubish Diamana S+ shafts.

The S= should launch higher than the Phenom, and you may want to tip that shaft. The best advice would be to find a facility which offers fittings…

Could someone tell me what TVD wedges are?  Cameron mentions them in one of the postings and the Vokey sight also mentions them, but I have never heard of them.  What are their specs, advantages, characteristics?

Thanks,
