Hi Kelly, I am contemplating wheel builds. Thinking 32 hole, Velocity polished A23 rims (they seem to address some problems with Velocity Synergy in high dish). Of course I want dynamo lighting. When all is said and done, it is an expensive thing to do. Got to looking around and found Shutter Precision. <http://www.sp-dynamo.com/index.html> (SP) I was also cued by the appearance of an SV-8/Velocity Synergy rim offering in "New Stuff" at the Rivendell site. SV-8 looks to be very price competitive. PV8 seems to be build like a brick outhouse but loses the price point advantage. And there is the question of getting them in the U.S at all. That being said, now that you have had the SD-8 for a year, how is it holding up? They do make some bold claims on their web site. There are some favorable reviews (google search, Bicycle Quarterly).
My use case is front and rear lighting for diminishing light following sunset. I doubt that I will randonneur hours into the evening.
