As far as my comparison, the thing to me is that the 104 probably has better tires at least with the foams. The rim is larger, and the compound a bit more suited to carpet, but the geometry I think holds it back
I've been trying all sorts of combinations, including Ride 103 rubber, Ride 104 rubber, F109 foams and the Tamiya F104 foams. On a warm surface (outdoor asphalt), the Tamiya B foams are still my favourite - they grip up well and are nice and progressive. The F109 foams were pretty good as well, but aren't as progressive when they let go.
Got a set of TRG Superions to try this Tuesday night, along with the high traction T-bar. My fallback is the softer Ride 104 rubber set.
