Hello, i would forget the spacers and get an Adjustable VTA base like the Michell or VTAF(on the fly adj!). It's a lot more accurate and simpler to do.
I haven't heard the BP2, but i really like the 10X5. There also is the Denon DL-103/transformers, Grado Sonata, Audio Technica AT33PTG, Benz Ace, Ortofons, etc. Get 2, they're small! Lots of choices, depending on your phono stage or system.
Have fun and enjoy, Alan
