I own one of each, got the Assyrian first and love it. It's a 60" #51@28. It wasn't built for me and is a few pounds lighter than I wanted so I had Gregg build me an Elkheart 58" #56@28. I went back and forth, recurve or longbow, before ordering the longbow. Reasons? The Elkheart doesn't require a stringer and is easier getting through the briars. As to differences in shooting, both are quiet, shoot where I want them to and fit my hand perfectly. I'm saving the recurve for when my shoulders force me to drop a few #'s.
I haven't chronoed them but the recurve is point on at 50yrds with a 550grn arrow, the Elkheart is point on at 60yrds with a 600grn arrow. Split finger, middle finger in the corner of my mouth.
