Might I suggest making sure it's your
clubs holding you back? At a 26 HCP, There's obviously more effecting your game than just
clubs.
How many lessons have you taken? How's your swing?
If you're sure it's time to step up to new gear (ie your swing is where you'd like it to be), might I suggest finding
clubs with low offset, (as more offset
clubs will promote more draw - and too much offset makes for nice hooks), and maybe something along the lines of a combo set? This will give you more workability around the greens, and a little more clout with your short
irons.
Good luck in your search.
