I'm gonna make this one quick:
Been using Glayzer on FH on Innerforce Layer ALC for a month. Found myself twiddling it to my BH too, so now I have it on both sides.
It took a few sessions to get adjusted to the activation, which to me felt like I needed to break the rubber in. But after adding a second Glayzer to the BH and instantly getting the right feeling, I'm sure it was me breaking in rather than the rubber.
This one does it all as an allrounder. It's not excellent at anything, but it works well for everything. It pushes, chops. loops, drives, blocks, and smashes with good, Intermediate player level quality.
Who is this suited for? Allround and OFF- intermediates who play spin and placement over power. I also see OFF+ power players being able to learn a lot with this rubber, but they will likely be moving on to something more powerful when they've been playing intermediate levels for a while.
I found this to be playing much, much more dead on a 5ply and I wouldn't recommend it unless you want to learn to generate good power and have the ambition of moving on to fiber later on. On Innerforce, this is an easy rubber to play.
For outerforce alc on forehand try 2mm Hammond z2, or D 05 (1.9mm).
They faster and just as controllable and less overshooting the table than 2.1 Glayzer.
On backhand Glayzer 09c (2.1) or Nittaku c1 (2mm). - G09c more control though. I found I can hit hard, as the blade has plenty of dwell more than normal carbon blades. Found its a bit more direct than innerforce and therefore can attack more. I used that combination (Hammond and Glayzer) on outerforce this week in competition and it went okay.
