Definitely I will have to choose "LAYANI", I have owned more than 30 high end cues (adam's, schuler's, Longoni's, Alcalde's, etc...) and the best cue I have found is "LAYANI", there are some elements in Thierry’s cue that for sure make the difference:
1.- The joint, it will not wear, super resistant and it is not affected due to temperature changes, wooden joint vary the hit substantially due to temp variations. Thanks to the cone joint the hit feels with no vibrations at all, more like a "pure hit".
2.- Inlay work, it is flawless and different from normal carom cues.
3.- The Layani tip, I've played for 10 years with moori's and decided to switch to layani tip it hold chalk much better.
4.- The ferrule, don't know the exact material but it is really resistant has thick walls.
5.- Plus is a handmade cue.
I had the opportunity to play with Fred Caudron in Colombia in June 2008 and by that time he played with a Layani grand slam, currently he plays with the same cues achieving incredible results, that says a lot...
