Yes, I understand the mechanics of a low deflection shaft. What I am saying is that the developers of these products did it to make use of junk wood. In the cue making world, the materials used are basically scrap wood. Charging $250 for scrap lumber and glue is basically fancy marketing taking advantage of an extremely gullible and uneducated consumer base. Their innovation was productive and seems to work. My problem is that it has demeaned the skill of classic cue makers. The shafts from my 1979 Richard Black hit as good or better than any laminated or " low deflection shaft."
And yes, I am aware that this is an opinion, so you don't need to explain what an opinion is to me.
You obviously don't understand the mechanics of LD shafts or you'd understand that LD and laminated/radial segmented shafts are mutually exclusive. Just because almost all laminated/radial segmented shafts are made to minimize cueball squirt doesn't mean that a solid shaft can't have LD properties.
I also have a problem with some of the marketing claims and believe that no company has shown enough due diligence to make many of their claims, but it is a minor problem because I am a firm believer in 'caveat emptor' and anyone who buys into marketing claims without doing their own homework should live with the consequence.
As far as using 'junk wood'...well, show me what 'junk wood' is and maybe I'll agree. I have shafts with sugar spots, low grain count, grain that runs off in the middle of the shaft, etc. that would be considered substandard shaft wood and they play great. I've also got a shaft that would, by looks, weight, grain count, etc. be considered nearly the pinnacle of shaft wood that kinda sucks.
Suffice to say that I don't really believe we know what 'junk wood' is.
Let's say that these manufacturers do in fact take junk wood and turn it into a product that repeatedly has similar results (which I think they do, in my experience). Let's also then presume that these results are within the acceptable limits of what is necessary to play great pool (in fact, I contend they are--I had my fastest break and run ever, less than a minute from the time I broke until I made the last ball). If these two points are true, then they have done the world a service.
Whether that product is worth the money is up to the consumer.
As a proviso...I am not replying to the OP...I believe he is an alias for someone else on this forum or simply a troll looking to stir chili. I am replying because I know there are a lot of people who poo-poo the efforts made by some respectable companies. While I don't use laminated/radial splice shafts, I applaud their investment and contribution to furthering the technology of our sport.
