a kirkham is top dog....its really a matter of $$...i call it the
$25's...approx $25K for a FF5, another $25 for a ERA another $25 for a Kirkham
....
I've never heard of sagging frames on a kirkham...David and his group are stand up folks and stand behind their product and the community!...You can probably have a Kirkham built quicker then a ERA...its all a matter of $$$
