Very interesting thread. When I started to use the TF, I had a hard time getting what I wanted from the reverse patch, but I realized that the key was the crossfade knob. This is a parameter not usually found on other devices, such as L6. That might explain why some users couldn't find their mark at first.
Once I got the hang of the crossfade, I was able to use the reverse preset with great success. So I would be an advocate of not changing it! More flexibility means more work initially, but it's worth it as far as I'm concern.
This is the reverse preset I'm using:
Mix 8
Dmix A5 B10
D. time A3/16 B dotted half note
FBK A0 B0
x knob 3ms
(using the expression pedal, i move towards the following)
Mix 28
Dmix and D time stay the same
FBK A80 B100
xknob 100ms
