I cannot claim to be a tip expert. However:
I got good use out of the LePro tip that came on my 314 shaft. This is not the LePro tip you can buy, but somewhere in the factory they squeeze them to a harder state then the LePros you buy elsewhere (sort of Milk Dud like--I guess). This tip started to requir a lot of maintainance. After a hard hit, there would be a visble dimple on the leather surface that I would have to be careful to avoid the rest of the night on delicate shots. You could see the dimple when sanding the tip surface. It was as if the tip got soft after the aforementioned maintainance wore through the harder leather, so I replaced it.
I replaced it with a Talisman hard and have generally liked this tip. It holds chalk well, has power, and touch, and does not miscue. One thing I do like about this tip, is that you can abuse the tip (hitting a cue ball really hard) without leaving a dimple in the surface. A very gently scruff with 120 grit re-enlivens the tip after weeks of use/abuse, now and again. This tip has not mushroomed in over 1.3 years of use (averaging 8-15 hour per week of use). {I also know that Taliman tips are not highly regarded here at AZB}
Your milage may vary.
