The answer to this question is highly dependant upon the pips you decide to use on your backhand and whether you mix chops in with loops/hits on your forehand.
Tensor pips such as D.TecS, Piranha, Kamikaze etc are very sensitive to blade speed and should only be used up to All+, possibly Off- if you have good hands (meaning you are good as softening your grip at the point of impact).
Hellfire, Dornenglanz I and Giant Dragon Talon are best with All to Off- blades for a pushblocking game, however they can be used with OFF blades as long as you chop block anything closer to the table and chop further from the table. If you chop on the forehand then you have to step back to Def to All+.
I play the chop block, chop, forehand loop/counterloop/hit game with Dornenglanz OX and found I could play with a Viscaria if I stuck to my tactics and loosened my grip when using the pips. Dornenglanz is the least sensitive pip I have used to blade speed. Hellfire was tough for me on anything with a harder outer ply above OFF- speed. I think this boils down to the stiffness of the pips, Dornenglanz has fairly stiff pips which forgive a faster blade up to a certain impact force, which I don't allow to be breached if I can help it by using soft hands. Hellfire and all the tensor pips are softer and bend easier so the hard and heavy plastic ball needs less force to bend them and get into the wood making them more sensitive to the speed of the blade.
I have had success with tensor pips and the S&T Zeus blade, Dr N. Titan and Joo, but for my game which relies on forehand attacks to win the point (good players tend to use the pips against you rather than give you free points by sticking it in the net or sending no spin pushes long) I prefer to use Dornenglanz on OFF blades. I am about to try the Clipper Oversize WRB to replace my Viscaria/Double Day Terminator as I think the Koto outer and carbon in those lessens my ability to dampen the speed on chop blocks closer to the table just that bit too much, and the Clipper won't be that different in terms of forehand speed.
Another tip, the new Sauer & Troger Super Stop rubber in 1.9mm can be used in combination with OFF and OFF+ blades and you can play LP strokes with it. If you don't chop a lot (although it chops pretty well) and rely more on push/chop blocking then this is a better option with the plastic ball than OX LP, much easier to hit with and distribute the balls to awkward angles, as well as dropping the ball short over the net to avoid getting killed. I think this Toni Hold kind of classic anti will be the new go to in the plastic era for pushblockers, OX LP still have their place for those that chop further back as much or more than they block at the table.
