A perfectly flat ferrule and tip is essential for a successful installation.
I find the Samsara tips to be a bit unpredictable, but lately I have been using Loctite 401, taking care to make sure that the ferrule is 100% flat. Applying a small drop of glue to the tip, wiping of the excess and sanding the back of the tip when the glue has dried, scoring the tip and ferrule. Gluing the tip on as centered as I possibly can, keeping pressure on the tip with my tailstock and letting it sit for atleast an hour and letting it cure 24 hours before I work on the tip. When cutting down the tip, I make sure to not het up the leather and cutting it as close to the ferrule diameter as possible, so I minimize the amount of sanding to blend the tip and ferrule and thus, potentionally heating up the tip.
Cutting them down to a more practical length seems to be key. I often see the tips not being cut down enough and then they tend to pop off.
Some players miscue more than ohers and if I have a player that has a bad break and often miscues I recomend another tip.
I use the same process on White Diamond tips.
