choosing a tonearm for my new michell gyro

Hi everyone,
I am buying a new michell gyro TT and the dealer offered me a choice between two tonearms:
1. Jelco 750D 
2. Origin Live Zephyr (for this arm I add my old TT project RPM 5)
currently I will continue using my Ortofon Rondo Red but itmay be replaced in the future.

I know the OL is priced much higher then the jelco but the reviews are controversial.
any suggestions? 
Thanks
