Well it behaves until it wants not to, and it should not misbehave as much when dinged IMO with the specs it is sold with. Mine seems to be behaving better recently, but hate tempting the gods saying that:)
If you are going to miss the ding with it make sure you miss smart, not wrong side.
IMNSHO I also think people expect too much with meter speed specs anyway. The last second woosh has always been there (often v noticeably so with irons), and nothing will ever be perfectly linear. If people want tick tock same with every club every day ain't there to be found, just got to run it through to get a feel and then do your worst.
All that said it does have those extra yards, shows excellent stopping power, can conjure some marvelous shots and so stays in the bag of most for that. It also gets sworn at when it misbehaves. It can root you good and proper if you can't ding it, and miss by much at all it will get sworn at very vigorously:).............All that said it's not so hard to often get close to ding with, for many, with some practice.
