Ditto on what VeganRay said Aaron said. The Summit is my kind of putter. The VP is my kind of putter off the tee. Stiffer is being tweaked. Look for us to be able to get tester samples out in a couple weeks (and don't quote me on that, maybe I should say a few weeks. - )
Also, I may be able to make an announcement one way or the other about a release date for the VP in the coming weeks too.
