All three rubbers are unique and different.
As different a rubber MX-P is, if you are a T05 user, usually, you can adapt to MX-P using the same strokes with not so much difficulty adjusting, yet the shot result will obviously be a different on than T05.
T05 Hard is another animal from T05, the adjustment may be easy or hard depending on your kind of impact.
T05, if you use it for hours and hours a day every day, will begin to wane at the 50-60 hour mark and be a shell of itself at 80 hours, near unplayable at 100 hours. That sounds real bad, but many rubbers are not designed to still be performing after 80-100 hours.
You can take off T05 and do a light tune job to give it a few more weeks, like say 40 hours more... maybe you can do that twice, but that is pushing it.
MX-P will have its built in tuner begin to wane after 20 hours... prolly totally gone by 40 hours of play. Big deal, at least for me it isn't a big deal. MX-P without tuner is perfectly playable all the way to the 200-300 hour mark. After that, it is time to rip that sucka off ur bat and toss it.
I see where Donn is coming from, I believe (just like TTD Dan in his reviews) that a DYNAMIC TEST using the likely shot impact scenarios yields a lot more meaningful info.
Just like NDH (Should I jack up hiz initials again?) touches on, we as players all have our way to impact the ball and one rubber that is great for a player may be garbage for another.
An example of FLAMING Hot Garbage as a player is none other than Der_Echte his-self.
As much a growd-up dude he iz, at 110 kg, and as much a MACHO MAN Der_Echte wants to be on the FH wing... Der_Echte simply doesn't cut it for Macho man Table Tennis on FH wing with the harder sponged rubbers. (Unless it is counter-looping, then it is game-on)
For the majority of shot situations I use FH, Der_Echte is a total SOFIE... so if I would use a Tenergy, it would be T05FX... FREEKING F. DAMN X. Period.
That is an example real life where a review of a top rubber like T05 hard would have next to zero applicability to how I play, since what I do on FH is not very well optimized... I would be fighting against the rubber, the umpire, the janitor, and anyone else in a 2 km radius.
EVERY ONE should first understand themselves and what they do first, then be able to tryout for self. Unless one know WHO is reviewing and WHAT they do and HOW they do it, there will never be an effective understanding or relevance of the review.
