Any down sides of going Borgeson vs Firm Feel?

I think anything is an improvement over the stock vague feel and over assit.
my 70 aar had the optional fast ratio power steering box, and except for my rack & pinion police intrepids, and 5.7 hemi police charger, it was the best handling mope I've ever driven. Come to think of it my 79 300 had pretty good feel, too, but that was a factory "firm feel" police box in those.
