I haven't heard the F9 (in any version) so take this FWIW...
First and foremost, ask Soundsmith what the compliance will be on an F9 with their OCL Ruby cantilever. That's crucial information.
I believe some stock F9s were highly compliant cartridges (like 25 X 10-6 cm/dyne) and as such were optimized for low mass tonearms (like a Grace, lol). The OL1 is about double the effective mass of a Grace, not terribly high so it shouldn't be terrible, but not optimal.
Putting a cartridge on a *much* higher mass arm than it was designed for will (in theory) stress the cartridge suspension and cause it to age faster than it would on a more suitable arm. The cantilever might be driven to its limits of travel by high amplitude groove modulations, in which case you'd hear distorted or clipped dynamic peaks.
All the above is theory and again, the OL1 is not *that* high in mass. It's also possible the Soundsmith retip may result in lower compliance, which would help. I've no experience with the F9 and defer to those who've heard this combination for real world impressions.
