Yes, there is room on the tonearm for the 10" VPI I know...probably the 10.5i, too.
You need not buy a tonearm board....you just drill out the opposite end of the armboard and switch arms (and directions of the board, of course) as needed. VPI will
probably drill it for free for you if you buy the 10.5i from them.
Call VPI on all to be sure
