I too have had A LOT, LOTS, AND STILL MORE problems with delam issues with Talisman. In fact you can no longer have a Talisman installed at Varney Custom Cues. A lot of Talisman players don't even notice. Look at the layer lines on the side of the tip. All lines should look the same thickness. When you see one line thats darker, thicker...BINGO...you have a delam. Press gently on the side of the tip and you can see the dark line seperate. The reason the line looks darker is due to the chalk that finds it way into the crevice. I've seen this way too often with Talisman tips. Most players don't notice until they loose some layers.
There are many superior tips on the market. High quality tips such as Moori, Tiger, Kamui, Molavia, will give you no such problems. In fact I'll go so far to say that probably 9 of the last 10 pro players that I've replaced tips for...are using the Sniper by Tiger. The secret with the Sniper is to have it correctly installed...a lot of hacks out there are turning them down on the lathe like they would a Moori...and are ruining them. When correctly installed...the Sniper is superb. Inside english shots will make your knees buckle. I played with the soft Moori for years with no complaints or reason to switch. Now fresh Snipers reside on my personal shafts.
