Sometimes user surveys don't mean a whole lot.
I like what the W brand do: create a small batch of prototype frames (model doesn't exist before) and let the users (pros and focus group folks) play around and get some feedback.
The first step towards a PD 98 (and Tour)... Well, is to simply scale it down to 98 but everything else AS-IS.
Not until the players actually playing with it, many of them (particularly those who thought they can't play with anything smaller than a 100) will not even know that they will actually like a PD 98 better.
I sincerely look forward to Project One-Eight (or One-Seven B??) to be the PD 98 (and Tour), I'm almost certain that the excitement and sales success that it brings will Way surpass Project One-Seven.
i.e. unless there is another PS 16X19 that opens up the center MAIN strings spacing more...
(why not? there is a 18X20 for the dense lovers already
