Stone,
There is a large company in my area that buys 4 TT a year and puts the Toro T-Bar on them. I ran them once, they were okay. I suppose if you hooked on the T-Bar (As I'm sure you are, for I, too was a Toro diehard) then that set-up would be awesome.
I'm kinda surprised that Toro hasn't offered a TT with the TORO 62" deck and T-Bar. It'd be a great mower.
By the way, you'll get over your T-Bar affinity once you run the new Exmark Turf Tracer ECS: Enhanced Control System.
