I've had about six Adcocks of different make and model, all but one by O.L. The limbs are definitely "wiggley" compared to your typical longbow. But I would not call the fragile at all and they can easily handle a 30 inch draw length...
That's what I also noticed about my Morrison longbow.......the tips are really soft. different feeling than any longbow I've ever handled. It almost feels like I could just yank the string right off. If I squeeze the limb and string together it feels almost like the tips aren't even under any tension.
I do know it's super fast and smooth as heck to draw back to my 30".
Who was it that said Morrison might be using OL's limb patent? Sounds just like my bow.
