Hey, Dixie!
I’m totally in agreement with Trish, and in fact, my Ormiston was my “transition” flute, too. And like Trish, I really just prefer the Pratten setup I think – plus I’m plain stupid in love with my Hammy. (It’s a glutton for punishment thing, I guess
)
But I’m sure glad I had the Ormiston first – I might’ve given up if I’d gone to the Hammy first! 
I have average-size hands but very long fingers; nonethless I still use a sort of piper’s grip, esp. with the Hammy. But whenever I go back to the Ormiston I have no problem after the initial moment of “spaghetti phalanges.” And the one thing I do like about it is there aren’t any blocks to get in the way of that grip; in fact, I find the key setup on my Ormiston far more user-friendly, esp. for those “Boehm crossovers.” So I don’t think larger-handed players would have any trouble with it, either.
Seanny, I have no problem getting a big sound out of the Ormiston (although the Hammy seems to have a quality that makes it “cut through” or carry more in a crowded session, but that’s a function of the Pratten type I think), and it doesn’t take a lot of air – once again, the question of volume really comes back to that dreaded focused embouchure concept everyone keeps talking about.
(I’ve heard John Skelton create a small sonic boom on my Ormiston, so I know it can be done.
)
Another thing I like a lot about the Ormiston is I can put more of an “edge” on the low notes more easily than the Hammy – it’ll tolerate a serious frowning embouchure without breaking, whereas the Hammy requires more subtlety. I can do it, but I just have to think harder and it has required knowing the flute a lot better.
In fact, when the Hammy experienced an unfortunate St. Pat’s Day accident, I played the rest of our gigs on the Ormiston – and I was AMAZED at how I can make that thing bark now! So it’ll do it; it’s just a matter of knowing it well and seeing how far you can push or pull it.
Bottom line, I think George makes really nice flutes at a really reasonable price, and for Boehm crossovers I believe Trish is right … they’re wonderful and a truly great value.
Mine has certainly served me well.
Hope this helps, and have fun!
Best,
cat.
