Used EL-S and FX-S for a full training session and then a match later in the week.
First up - I mentioned earlier that I didn't like FX-S on my BH side at all. Turned out that it was a bad glue job. Not something that I struggle with usually, but it got me this time. Once I had re-glued it, the feeling of the ball just flopping off at low impact speeds was gone and it played much more predictably (as you would imagine). That said, it still isn't my cup of tea overall.
I haven't really changed my early opinion of EL-S much to be honest. It has amazing spin through the low and medium gears, good spin on harder hits. It's sensitive to incoming spin in passive play, but not that bouncy (excellent for serving). Looping against backspin is incredible - probably the best ESN rubber I've ever used in this aspect of play. Having used it back-to-back with T05 now I'd have to say that the medium-gear throw is slightly lower overall and probably resembles T80 a little more - I felt it needed a little bit more effort when counter-looping than T05 to get the safe arc required, more noticeable from half-distance. But these are very small margins - for this loop-reloop-counterloop game, EL-S is still super close to T05. On harder shots the arc tightens up somewhat and becomes a bit flat, but for me this is a good thing and I'd give EL-S a definite edge over T05 for smashes and hard punch blocks. If I had to sum it up in terms of being a tenergy competitor, the headline would be - imagine T80, but with less low-speed bounce and a little more top-end stability. I have to wonder if boosting it would bring it ever closer to tenergy feel and behavior, but that wouldn't be my aim anyway - personally I prefer EL-S as it stands out of the packet against Tenergy.
As for FX-S - the re-glue job helped a lot with how comfortable I was when using it for sure, but it's combination of spin sensitivity and non-linear catapult is still too much for me. Many players like this kind of rubber (T05-FX is like this, only more so, and some people love that), but it's too off/on for me and requires, well, too much concentration for me to use if I'm honest. It's demanding in awareness of incoming speed and spin in a way which reminds me of T05-FX, and I would prefer the extra linearity that EL-S's harder sponge brings.
I'll write up some more structured reviews for the review centre soon.
