I agree with most of that but still would recommend it
Setup: H3 39 boosted on FH, G09C unboosted on BH on a heavier 92g Falcima
Pros:
- light: 44g cut in 2.1 mm
- low catapult which I like
- low tackiness but better than no tackiness at all
- short game
- not to reactive to incoming spin
- throw angle is higher than H3 but not too high for me
- topsheet grips the ball very well although that depends a bit on the balls used like with H3.
- enough speed to finish points even with BH
- same with spin. Not on H3 level but I would say at least the same or more than some older ESN rubbers like Vega Pro, G1, MX-S, V>15.
Cons:
- speed and spin only if the stroke is properly executed. Due to the sponge hardness this is far from easy to do when put under pressure in real matches.
Overall I would say: Good hybrid for FH. On BH it depends on playing style and how that rubber behaves boosted. Unboosted too hard and not versatile enough for me but good for training.
