Tone Master Twin firmware update – which one?

[Per Berner]

Hi! My Tone Master Twin (the black one with Jensen speakers) has the original firmware, and I intend to update it to improve the reverb control (it goes from zero to way too much after turning the knob just a few degrees) which the update is supposed to fix. But there are three different updated available on Fender's site – one specifically reverb-focused, RvbMod_v1.1.35, and two others, a general one, v2.0.30, and a vintage v1.2.0.7.

Anyone who's tried all three, who knows if they are worth installing and how they affect the sound (other than reverb sensitivity)?
