2021 New Blades

They have all limba outer. Are core and medial plies made out the same material, no matter thicknesses?

They already have enough IF ZLC blades to start a collection :)

I played a lot with the original slightly bigger IF ZLC and now with the Apolonia. I have no doubt IF ZLC construction is a winning formula for beginner to intermediate club players. Slow enough to learn fine with slower more controllable rubbers all the way to where they want. 

Hypothesis: The top players go more towards ALC the same way tennis pros go with higher tension: since they have strength and speed in reserve, they prefer predictability with higher tension even though it requires more force into the stroke. The tt pro will prefer ALC for the same reason: less dwell, less elasticity gives more control despite the required additional muscle which they do not lack.
