Mueller shows (from softest to hardest) Elkmaster, LePro, and Triangle. A local repair guy swears that Triangle is softer than LePro. I have heard this before, but haven't found it documented anywhere. I throw it to the masses to see what you think. Thanks.

I classify them as similar, ie medium/hard. If you take a box of each you'll find some harder LePros and some harder Triangles. Both have their flaws; the LePros tend to "chunk out" around the edge now and then, particularly when they get old and thin, and in a box of Triangles you may find 10% or so that are "spongy". All in all, I prefer the play of the Triangle, and it seems to take chalk better because of it's coarser fibers.

More or less, ditto.

If quality control was tight on all of those you mentioned, then the Triangles would be hardest, LePro next and Elkmasters softest. The facts of life are that the LePro tips vary in hardness in a box of 50 far more than either of the other two brands, and the really hard ones are harder than the basic hard Triangles, but in general the LePro tips balance out as softer overall between them and the Triangles. Confusing ain't it...sid

To get a definite answer for this query, one should be familiar with Mohs hardness scale..ranking from 1 to 10
1 Talc
2 Gypsum
3 Clacite
4 Fluorite
5 Apatite
6 Orthoclase
7 quartz
8 Topaz
9 Corundum
10 Diamond
Now after assembling a sample of the above minerals, we can compare hardnesses. If you can scratch your tip with a sample of the above..it's softer ...but lacking the above minerals...
your finger nail comes in around 2.5..therefore if you can scratch a lepro, and most assuredely, you can scratch around 10 in a box of 50...they be soft!!!
If it takes a penny to mark it ...that makes it around 3..or med
If you have to use your knife, around 5.5...that's like J. Lo walking into a room sans clothes, and you've just taken yer Viagra tablets.
Or we can use a Rockwell or Brinell scale...your better rooms have these available...hope this helps

triangle is much harder than a lepro, its at the top of the list if you like hard, right next to morri.

Thank you everyone for confirming my sanity, especially with the inconsistency of hardness with the LePro.

??? Don't Mooris come in three different flavors of hardness? Aren't there tips that are much harder than Mooris ever hope to be? Didn't virtually everyone agree that the range of hardness in a LePro overlaps the range of hardness in Triangles? And that an average (mean/median, if you test each) Triangle is harder than the average LePro?

OTOH, every LePro I put on ends up harder than the hardest Triangle I put on. Every soft one ends up... left in the box with a lot of bite marks.

I can't see how it couldn't help.

Carl...If you are like me, or have a tip customer who like hard tips and play with a McDermott line or Viking, you can fairly easily define the hardest LePro tips by observing the web pattern on the glue side. The tighter the pattern the harder the tip. I finish my selection process by sorting 3 or so from a box of 50 and then drop each on a glass surface, listening for the highest "ping." That'll be my LePro, and as far as I know McDermott and Viking installs these stock on their factory cues. There's a reason for that, they fit the hit in those cues...sid
