I have a set of dale scales on my esee 4, they are great. the fit and finish was excellent on mine everything lined up perfectly, they are not individually matched to the blade so there not quite as perfect as the standard handles but bloody close.
I didnt mind the standard scales but I did think the handles were a bit short, I could still use the knife fine but now with the 1/2 inch extra length and contour its perfect for me.
if you go the custom route you have to buy the blade, handles and sheath separatly. Dale is great to deal with good luch with whatever you decide.
