While we're on the vague subject, I have a Howard low D (plastic head, tunable) Can anyone suggest a good way of tightening the joint without stressing the head too much? it's already cracked but I wrapped it in insulating tape and still sounds/plays fine. A new head apparently costs £30!!! Bugger that fer a game of sodgers. Anyway I can't get it to stay in place while I'm playing, it creeps down the body of the whistle :-(
