Laces only for me (so far). I would want a disc shoe to try it, but I have not yet. Laces have been working for 30 years - though I do really think this is a nice piece of technology.
I was gifted a pair of Footjoys with the BOA closure, I liked it. I just don't like how they're more expensive. I will gladly save the few dollars and get the laces.
I haven't given discs much of a look for golf. I have looked at them hard for wading boots for fishing, but always came back to I wouldn't want to be in the backcountry and have one pop. With laces it's easy to swap a new one in while discs is harder.
Now thinking golf I may try them on the next pair.
