I'm not going to say this about all single piece tips. But most I've tried will not last as long as a layered tip. I get one year out of my layered tips. And they consistent throughout their lifetime. The singles were mushrooming, glazing (badly), and would only last 3 months. I could scuff the singles I was using and they would glaze before the next weeks play. Constant attention and maintainence was required. Haven't had any of the problems you mentioned with the layered tips I'm using now. Also the single layered ones I was using seemed hard on the outside, and soft on the inside.
With the layered, they seem consistent all the way through. And good ol Masters chalk holds on just fine.
Unless you are buying a hard layered tip you might get a year or more of play out of it but 10 months of that year it will not be the tip you purchased... Soft turns to medium and medium turns to hard.... I won't debate anything else tonight but that fact.... You buy a Ki-tech Soft and a year from now it will still test as a soft... Buy a medium and it will still be a medium....
Single layered/bonded vs layered... There is no way a layered tip outlasts a bonded tip if both go thru the same types of processes and QC...... Hards... MEH... Do what you want.... but the Ki-techs don't delaminate or glaze to the same level that is seen on the layered tips out there...
Your observation about soft in the middle and hard on the outside has a small amount of merit for single layered tips but it has more todo with the fibers than the actual construction... At least for us... Every tip we make is pressed at over 2000psi... Since the molds touch the outsides of the tip only the surface area will be tighter and feel harder than the center of the tip if you have it cut down to half height... Thing is as soon as you have chalked it and hit enough balls with it to lay the cut fibers down it will test right back where the tip was originally at full height....
Layered tips changed the game.... Mr. Moori realized that Japanese pigskin was more elastic than the hides in use and wanted to use the Japanese pigskin to make the best tip ever made.... What I see now makes me chuckle.. You have layered cow, water buffalo and who knows what.. Layering those skins instead of pigskin makes no real sense... Layered they will never measure up to what Moori did... They just want to jump on the layered bandwagon.....
The original medium Moori was the holy grail of tips and Moori lost it when the went into high production.... What If I told you our medium hard Ki-Techs test the exact same as those tips and they are solid.... How many even can remember what those original Medium Moori tips felt like?
Moori changed the game and I fully intend to change it back and charge less than what the premium layered tips have been garnering for at least a decade.......
I have the chemicals, leathers and testing equipment to match any layered tip out on the market..... You have a tip you LOVE?? Cut it off and send it to me... I can send you the exact same tip in a solid version over and over and over that will hold up for months.... We haven't started the custom tip design model yet but it can be done... It just may well be high price in the design mode but once the formula is done the tips would be the same price as normal Ki-Tech Grades.... 3 for 25 and they would be "your" tip.....
wow... off the soapbox...
