Adams XTD Ti 21*, adjustable +/- 1.5*. Matrix Red Tie Stiff shaft.
A touch lighter/finer/less 'thumpy' than the Ping - I don't think it's actually lighter, just plays that way. From my 'spare' bag and I have a 18* too - as going back, in that bag, to a single 'seriously thumpy' Rescue Mid!
I've got a Nike Vapor , with stiff blue diamana shaft. It is adjustable to 22 degrees, but think i have it set to 21 at the moment. It's a universal wrench attachment but i don't have a spare one as i use the one i have for my driver.
