I have always preferred shaft wood that is of the honey color over the white stuff but that is a personal preference.
I am not a very high level player either.
I have cut down a few hundred maple rounds and one thing I have learned is stressed wood will warp from the first cut.
Relaxed, stress free wood will stay straight thruout the process.
Perhaps by the time I have cut a few thousand shafts I will be able to expertly grade them but for now the blanks I buy only about 50% make it to a cue.
Point is ... I am no expert and need to depend on the ability of others who are more experienced to advise me accurately on the wood they sell.
From what I read you do not have the level of experience that gives me a warm and fuzzy about spending top dollar on shaft wood.
Just being honest here.
Another thing is that most cue customers avoid any figuring or coloring in shafts.
They want the nice white, straight grain and the more ring counts the better they like them.
So if I am going to make a cue and plan on selling it ... that is the shaft wood I look for.
