Thanks, still not 100% satisfied, they are too large for my liking and not sure how well they will hold up since the tubing the nut is on is very thin and a bit twisted, prone to cracking from fatigue. Going to give the 1/4" a try but need to pick some up first.
Here is the alternative using the stock pipes.
If the stock pipes weren't so damned expensive I would cut them near the head and join them to the copper.
