My top 'wish I had it back' bow would have to be a Super Shrew Delux, 57#28", 58" gray actionwood with black grip/shelf, black and white micarta riser and tip overlays and a gloss finish. It said PBS on it, I believe it was a donation/raffle bow by Ron L. Pretty little bow, got it used, really liked it.
Then there was a Hill Big Five, 68", 53#@28", Ebony riser, tan leather straight grip, matte black glass over bamboo. Sweet.
And a 63", 51# Green Mountain D-style longbow with Cherry limbs and Cocobola riser....
Come to think of it there's a number of bows I wouldn't mind owning again. Goes to show there's no such thing as a Holy Grail bow. Its all in what you make of what you have.
