I have several longbows 66", a 62" RER longbow and a 62" Blacktail recurve. Love 'em all!
Having said that, I have a shorty on order with Greg Coffee (Java Man). Currently signed up for a 54" Helms Deep recurve, but seriously thinking about calling Greg and asking him to switch me to an Elk Heart longbow. I shot both at the Kalamazoo Trad Expo and shot both of them as well as any of my longer bows.
One of the things that intrigues me about a short Elk Heart, is the way I could order it as a 2-piece. I'd then make a new back quiver with a separate pocket for the bow which would not stick up above my arrows. At 74, I don't anticipate climbing any mountains chasing goats, but I just think it's a really cool option.
