Main change recently was the single lever coupler, replacing the pioneer couplers. Some people with the single lever coupler say it leaks. I have the pioneers, as I had on my BX, and I really dislike them. Maybe if I had the single lever I'd dislike it for leaking. I'm getting used to the pioneers, as my hoses wear in a bit they're easier to get on and off than they were - the first few times I was cursing the fact that NZ doesn't import the single lever coupler. For some reason the second hose from the top just never wants to connect, and it's a bit cramped between the loader and the loader frame and tractor, so you can't get a good angle to push it on easily. Anyway.....for $4K not really a thing that'd change my mind.
