Advice on Adams Hybrids please

Nice one all, seems there is love for XTD and DHYs as well as opposed to earlier in the thread, I know it's very subjective. Certainly agree that the shafts are good, no issue getting the Idea airborne so happy enough to plough the Adams road further. Like I say, and again a very subjective measure, I was trying to get a feeling for how people viewed the feeling at impact. I think this has certainly shed some light on that. I fear a clicky impact won't appeal, and I'm a big believer in shelf-appeal (it won't matter to some but it makes a difference to me to love the club I'm taking out of the bag).

I've just picked up a Mizzy MP Fli Hi 4 iron (the ones with the light Nippons) to bookend my 5i-PW set, a few smacks out the back field suggest it goes like holy snot. So I need to get out and figure out where that sits with my current set up and 4h. I've also just added a 3 wood and having never had a fairway wood before it's really added a significant new option. Filling the gap is the next step and from the advice above I think the Pro might suit best, though I'm confused as to why they've made them in 18, 20, 23?!

Seems a really small gap from 18 to 20?!
