Jack - I know you have good string knowledge, but are there any multi's you like? You could try full bed, strung low. Also, the new Dunlop Biomimetic 200 16x19 specs look interesting (on Dunlop's non-US English part of the site), and I think they might be on TW on or around Feb 1.
I tried the Donnay and I liked it, but felt arm fatigue after a few hours of hitting; great stick otherwise.
I am going to test out my OHBh with the new Steams when the demos are out in 4 weeks and see how that goes. Good luck in your renewed search!
