I have 2 Northern Mist bows from Steve, a 66" 50#@28 and a 68" 55#@28.
I filled out a request for another back in October and haven't heard back, so he's booked out a bit.
I have other longbows in lengths from 60" to 68." Personally, I prefer a longer ASL, at least 68." Not sure I'd go any longer (68" is about as long as I can fit in the ol' F150).
I know some folks prefer shorter bows for easing around in a tree stand and ground blinds, but I almost exclusively spot and stalk so don't find the 68" a hindrance.
Not sure exactly what forgiving means, but I find the longer bows smoother to draw and seem to feel less stack.
Another brand to consider is St. Patrick Lakes, made by Erik Hoff out of Minnesota. I have one of his 68" Yukon Styks, which is a takedown. And because it has a G-10 riser it allows the option of the shelf being cut to center. From Erik's website, "G-10 is also so strong that it allows the option of the shelf being cut to center on the riser on an ASL. The shelf can be left 3/16" outside center just like my other ASLs but the option to cut really close to center increases forgiveness, tunability and makes it easier to get your eye alignment."
Pretty impressed with my Yukon and have already paid the $150 deposit to get another started with a yew core versus bamboo.
Lastly, don't forget about Howard Hill Bows, by Craig Ekin. I just got one of his Wesley Specials, 68" 50#@28, and it's a blast to shoot.
