FR 64s comparison Ikeda.

I have decided to go back to a FR 64s or change to an Ikeda tonearm.
Although I know the FR well (with SPU and FR 7 & 702) I have not heard the Ikeda. Or any other high mass arm suggestions?

Does anyone have experience of both? If so I will much appreciate hearing from you here or by eMail.
