What don't you like about the Model 2? I've A/B'd it on two-arm tables against several fine tonearms. It performed well and frankly embarrassed one or two competitors that cost alot more. IME it's a value leader at its price point. It's not the world's best, or even Frank's best, but it's a very good arm.
As for what someone "somewhere" said about compatibility with a Spacedeck, I say hogwash. Compatibility between tonearms and cartridges is absolutely vital. Between tonearms and tables? Not so much.
Provided the arm fits the table properly and doesn't unbalance the suspension (if any, not an issue with a Spacedeck) any arm bearing type will "suit" any table. You may prefer unipivots or fixed bearings or odd hybrids like a Schroeder, but the table it's on would have little to do with it. The interplay between tonearm bearing type and any decent table is fairly nonexistent. The idea that a table would "prefer" a unipivot vs. a fixed bearing (or vice-versa) is unsupported by anything I've observed, heard or read.
A cynic might suggest that Nottingham would hint at such a preference because that's the kind of arms they sell. Of course I wouldn't.
I suggest enjoying the nice arm you have unless/until you find something specific that it doesn't do right. Invest $110 in a Mint protractor and you'll get a 10X bigger sonic upgrade than any arm I've heard for under $4K. I don't know the Aro, but the justification you mentioned sounds like change for the sake of change.
