Lewm, thanks for details. No, my positioning arm has no demarcations at all; it's just clear acrylic. I did buy the P2S tool when Daniel brought it out -- as I recall, he offered a special discount to UNI owners. It dovetails nicely with the UNI to provide exact P2S for tonearm mounting. Sounds like the SMART essentially offers both in one package, without the need for all the separate templates.
