One some wouldn't expect right off the bat, but its my current #1 lady and so easy to shoot well:
56" Java Man Elkheart, half phenolic bow-bolt 2pc, 52@29
She and I have become one. I'm no Robin Hood by any means but I do ok on occasion
Well I have always favored longer bows, but this bow in particular has proven beyond a doubt for me that a short bow can be forgiving if designed properly.
Two days ago I took the Elkheart to its second 3D tournament and I got called out on a master stake shot that was downhill and had to be a good 50-55 yds or more. I had my moment of zen and drew and released focusing on the 3D deer. Me and the other folks gathered around all held our breath...wham! I nailed that deer! A cheer went up and when my friends and I walked down the hill to the deer we discovered it was a clean double lunger. Talk about a great feeling! I shot many more 8s and 10s that day, along with my share of 5s and occasional misses, but I know for a fact I wouldn't have shot that Elkheart so well if it had not had the thought and refinement put into it by Gregg Coffey, along with some LaClair mojo. Thanks Gregg for your artistry, thanks Ron for pioneering the short bow! I won't be taking any 50+ yd shots at deer in real life, heck even 25 is a stretch in real life, but I trust my Elkheart to do the job NO problem.
Two other shorties that are in the same league for forgiveness that I have shot are the Big Jim Thunderchild and a short Centaur.
As for longer bows, most tack driving 'long' longbow I have owned and shot is a 3pc Leon Stewart Slammer with either 66 or 68" limbs. Sniper rifle.
If your question is specifically geared toward 1pc "long" longbows I would choose a 1pc Slammer or 1pc Fox Triple Crown any day of the week. Both shoot 'lights out' and have craftsmanship to rival many others.
