What tonearms are compatible with a Scoutmaster?

I can see from VPI's site that the 10.5i is compatible, but the 12.7 tonearm page doesn't mention compatibility.

Are there other brands of tonearms compatible with a Scoutmaster?

I currently have a Sig JMW-9 and plan on getting a Dynavector XV-1s and want to get a suitable tonearm.

Thanks in advance.
