I had about a hour with the 75.1 Red ALC + DHS H3 Neo pair. To say the least, I had to be extra careful about my posture, because with this blade, the H3's arcs were much lower than usual - probably because the red ALC fiber added a lot of speed into my shots.
I felt the rubbers hard to control in the first half - it was difficult to dose low power shots - maybe because I should play with it more in order to break them in properly, so the control would improve.
So for now, I don't have really meaningful comparisons, but I do believe, that this blade is top end Off (almost Off+).
Interestingly, I received two more 75.1 Red ALCs, and both weight more than the first I received (85.4 and 83.9g), and also have lower ball bounce frequency (1452 Hz and 1500 Hz).
I will need to evaluate the low impact shots with another rubbers, but anything slightly above low, the fiber effect kicks in really soon, and add a lots of speed - only the Yinhe T8S is faster than this blade (from the blades I already know).
Dwell time is not really great, but not too bad either, just I need to make sure, that I stay conscious about my posture and footwork (thus I can go for more powerful loops), as this blade doesn't seem to forget even smaller errors - but my smashes with H3 Neo were got to a level I didn't experience before, and my long pushes were also painful to my opponent (if I didn't overshoot them with a length of more than half a table on "panicky" shots 😅 ).
