I am obviously not doing group buys anymore, but I can influence/start limited runs for HDS (which is basically me going "Hey Henry!
Very smart, Hogo. Instead of doing group buys, and many months of telling cpf about all of the supplier drama and QC issues, call them "limited runs." The first post in cpf can then be, "Hey, here is a picture of 25 complete build kits on the bench, including a really neat LED, the ___; the bins behind the build kits are all of the custom tubes and switches that will be used to customize each of the orders, including a new test run of 10 brass tubes and 10 carbon fiber 1x18650 tubes [I can only hope!]. Since all the parts are here and ready to begin the build, you'd better order quick, and your light will ship in 10 days or less after you place your order."
It is genius, because it is giving cpf and other fans what they want in custom and limited-run lights, and also listening to and responding to the feedback about the unpredictable and frustrating group buy schedules. Keep it up!
