I'll second Phil's response concerning surface adjustments. Best example in my experience owning Radical equipment was my first Reax Version 2 solid. I was so frustrated with it that I tried selling it on eBay; there were no takers. I tinkered with the surface once more and finally saw something I was looking for with that piece. I liked it so much that I bought a second Reax Version 2 solid. Now I don't leave home without one or both pieces.
