Hi Alex,
Yes I’ve used the DNA rubbers a lot and still use the hard version on both sides currently, I really like them. I would say the medium is and hard are both most effective because as you said the soft tends to reduce the power and also the effectiveness of the nice fast punches and blocks.
I like the hard best because it offers the most direct and snappy feeling compared to the other versions and I’m sure you like the feel of the hard on the backhand side of you like to punch and block. I tend to punch a lot on the backhand side which you also mentioned, this can be an effective way to deal with those heavy spin shots that dip down.
Tenergy 05 has quite a different feel I would say its more springy which can help with loop shots and when away from the table but it also means it’s harder to control opponents shots and spin and the control is as high as DNA for example.
It definitely depends on your game style but from what you’ve said to me and as you’ve been using them already I would probably recommend going for the DNA again but perhaps the hard on both sides.
Hope that’s helpful and anything else on this just give me a shout. Tom
