Tonearm hardware shuffle - recomendations sought!

I'm looking for suggestions on a tonearm given this situation:

I just bought a Nottingham Analogue Ace Spacedeck as a secondary table to my ClearAudio Ovation. I have some decisions to make about where to go with some hardware shuffling of tonearms and carts between the tables.

1st Table: ClearAudio Ovation + AudioMods 6 arm + MP-500 cartridge
2nd Table: NAS Ace Spacedeck

Here comes the wrinkle(s), now the fun begins!

I have an "MC" (ie low output) Soundsmith cartridge showing up in a few weeks. That'll go on the Ovation.

The table came with a space arm. It's still NIB so I could sell that puppy (this was my first thought) - or I could mount it + the MP-500 onto the NAS. Zero more $$ outlay and it will get me down the road for a while.

I've also read the AM6 fits well onto the Ace Spacedeck and then I could hunt for a better arm for the Ovation. (And sell the Space Arm.) I got a quote on the the VERY WELL reviewed Kuzma 4 point (11") and it's pricey! For the price of the 4pt11, I could get, say, an Origin Live Conqueror + another Soundsmith cartidge (a "MM" high output cart) + a degritter.

Both tables will hook into the Modwright PH9.0X. One on the MM input, the other on the MC input.

So there are lotsa of ways to go here. Anyone here have a good recommendation?

thanks!
