I think this is the first time hearing this argument against using wood shafts. I have been thinking for a while of switching from my Revo to a 314 shaft so I can get more feedback. Maybe even keilwood. But apparently wood shafts play different depending on humidity. Humidity changes depending on the season and geo location. I mean humidity changes a lot all the time, like a rainy day. I would rather not add another inconsistency to playing pool if there is any truth to what she is saying?
Hmm, her 2 rail safety kicks are off......a tight grain wood shaft can twist to ball more to make a good hit....and bank easier. Trees love humidity. Shaft stabilizer cures any humidity concerns.
I tossed out close to $1000 using him. He's not the answer. Find someone that will work with you and stand behind the set up if adjustments or new lens has to be made. My first few were using RayBan shooters frames and a custom lens. Explain what you want achieve. At first I wanted a field of 4-9'..the background was blurry. Years later the next pair were progressive that I got use to. I could adjust to the field, could read, and use them for driving also.
