Steve has been PM'ing answers to people. I just got off the phone with him and says he thought he e-mailed you an answer. I know from experience that this maple is pretty stiff and does not deflect much, especially with the short ferrules he puts on. or natural "no technology added" shafts these are pretty low on squirt.
Send him a PM if you did not get an answer and he will write you back as soon as he gets to his computer. He apologized as well.
I just got one of Steve's old growth shaft for my cue and all I can say NICE AND STIFF. . Steve did a great on my shaft getting my shaft out to me , I played with a lot of stiff hitting shafts and this is it ..... Thanks Steve. .
