When I first started doing repairs for others over 10 years ago,I bought a box of Le Pro,Triangle,and Elk Masters.
I've only bought one box of Elks since my initial investment. Since then,I'm on my 3rd box of Triangles,and 5th box of Le Pro.
For a LONG time,I didn't have the problems that people had mentioned here over the years with Le Pros going bad during install. These things happened,but never with any regularity.
However,I got to my 4th box of Le Pro and had almost half of a box blow up accordion-style while cutting them down,even with optimum cutting conditions such as fresh utility blades,etc. Several other tips went bad after I handed the shafts back to their owners,and had to be replaced to keep them happy.
On the other hand,this box I am getting them from now has been VERY nice.
In fact,these tips are so hard and dense that I've replaced a couple simply because the owner said they were TOO hard.
That complaint was what I used to hear most often WAAY back in the day when Le Pro was still the dominant tip on the market.
The tip I hear that about most often these days is the WB Water Buffalo or something similar to what Schon uses on their shafts,and comes on a lot of import cues.
The newest Le Pros are quite good
