Actually, I think SD-style short clips would be useful, but more as an adjunct to the existing clips. (And anyone who doesn't think Tim's and HJM's clips sound pro ... clearly hasn't heard very good pro playing :)!) But, anyway, different customers will be convinced by different kinds of info. No reason not to me as many things to as many people as possible ... eventually.
It is, after all, clear that these things take time and effort, and BKP are rightly putting the maximum of time an effort into making great pickups, rather than just tarting up the presentation of what they have. While I, as a would-be customer, would like to see and hear more detailed info, I know its in the pipeline and I'm comfortable knowing that the main work is the product rather than the product descriptions :).
