I once sold a 73 in smooth yellow bone to a guy who really wanted one. This was well before I began distributing for GEC, and the 73 was one I bought from a dealer (don't recall who), and it was an older model with a strong spring. The buyer was initially very happy with the strong spring and resounding 'thwack' it made when closing. He must have opened/closed it quite a bit, but after a week or so he contacted me and told me the bone was cracked at the spring pivot on both sides! The knife was NIT and in perfect condition when I shipped it, but now he wants his money back. As near as I could tell, by letting the blade snap closed, the bone couldn't take the shock resulting in the cracks. I wouldn't refund his money and he ended up sending it back to GEC for warranty work due to the cracks. GEC replaced the bone, but not with the original yellow.
So, I guess what I'm saying is that there is a down side to having too much power in the spring, both to the user and to the warranty dept. at GEC.
Just as an aside; I have a snappy Case ten dot 6318 stockman that tends to bite if you are careless about where you have your fingers when closing. I find the late model 81 moose to be a lot more 'user friendly' with its softer action, and my stiff arthritic hands seem to prefer the softer springs as well.
