I am watching for new stock on TW and they seem in short supply. 1-(3/8), 1 - (5/8) ... no 1/2 inch grips .... It has been this way for a while on TW and it does not seem like there is new stock coming in... This is what happened to my last Donnay stick right before it was discontinued. So the question is ... is there a change a foot? Do I need to be worried this is going away very soon?
