Yer welcome Juan.
The people that I have installed the single layer break tips for like them muchly.
They are amazed that a leather tip can feel as hard as a phenolic tip.
The leather breaks and spreads them around the table very well.
You are generally rewarded by getting at least one ball in on the break.
With leather, you feel that you have a certain amount of control on the break, something that you seem to lose using a phenolic tip.
Personally, I have never liked the feel of a phenolic tip.
I am sure the 11 layer will work the same as a single layer tip.
My friend uses a Samsara break tip on his. I use his breaker quite regularly. The Mad Man break tips do the same as the Sam does.
Not much effort involved at all to spread the balls around and sink one off the break.
