Greenhorn bows are, by most accounts high performing bows. With the exchange rate, they are very expensive bows.
Are they the top of the line? don't know, but would suspect that but what I've been told, the higher level Borders are excellent as well. Also, by all reports Bob Morrison's new ILF limbs are excallent as well. When you get into ILF limbs, there are the Win&Win, Samick, Hoyts (maybe) and the excellent Border limbs.
Stewart was the reall innovator with the Multi-Cam. Got to shoot one some years bcak, will try to pick up one up some day - this bow was a great shooter.
As to the issue of the recurve standing with a compund, some can, with some older model compounds.
Probably Blacky Swartz, if he sees this has some direct knowledge of the Greenhorn's and ahs shot some of the better performing bows currently in production.
