I play the UST Irod in my Dual's - superb shafts, readily available on ebay for £25 ish. Would absolutely recommend. Give's a mid flight. Other hybrid options in .370 are the Grafalloy Prolaunch (high flight), NV (low) and the Accurflex Icon HL (mid-high, great reviews, good prices from MidasGolf, and they will fit for you too). There is a UST V2 also, but more diffuclt to get hold of and a bit pricey compared to the Irod. Fujikura Banzai also around, but have seen some poor reviews - very harsh feeling.
You need to get the .370 tip diameter (as opposed to the .335 fairway versions). One complication is the ferrule - like the OS irons, the hosel has an odd extended section that requires a special under-cut ferrule to fit over it. Not absolutely obligatory - it's only cosmetic - I'm currently using an ordinary ferrule 'til I get some of the correct items.
