LF: Butterfly Werner Schlager blade

Better go for Xiom Axelo FL, still available and pretty good substitute. I use myself that blade with ST handle. It has more control than schlager carbon, but the same speed.

Axelo is not with Tamca, but another kind of thinner carbon, so it has more sense to the ball in my opinion. Otherwise - Sardius, Gergely Carbon and Primorac Carbon metal tag are sometimes a little bit faster, Moonbeam is also very fast blade.

The speed of the blade is never a factor for the speed of your strokes, sometimes you can make faster loops exactly with the slower blade, because it gives you more contact with the ball and ability to accelerate.

Yes, for sure Axelo is TOP blade.

Ignito is more slowly, it is blade for loopers that are looking for spin and control, I could recommend Ignito for players who love Primorac Off-, but need carbon and no-vibration blade, Ignito is definitely best for that purpose and Strato is a blade for short pips because has a very good speed and control in blocking, but it is with a lower throw, which could be helpful to stop heavy loops from your opponent via the pips. It is more a drive-smash-block blade, than a blade for topspin. All these are very spiny in serving too and have good control in returns.

Really underrated.

Anyway, good luck to Johny.
