Helius Omega Tonearm

I just purchased a Helius Omega 10" tonearm to mount on my Sota Cosmos IV. Does anyone have any experience with this tonearm, mounting tips or cartridge selections. I know its not a popular arm, but I find its design interesting.
no one?
That arm is a common choice for the Townshend Rock 7 table - very nice arm. According to a friend who knows, it works well with the Ortofon A-90.
Anyone else?
