Just an FYI on the BOA laces. So by being a tad neglectful I managed to fray the upper cable on my BOA focus boots. It held intact for the weekend and I was able to get a replacement cable (for free) from the shop I bought my boots at. It was freakin' simple to replace the laces and I would have done it just about as fast as regular laces except for a couple of things.
One, if the BOA has the coiler, before you back out the screws to release the old cable make sure the screw hole and the guide hole are showing. I just got the screw holes lined up. Sucked because it meant I had to put the screws back in making the coiler do it's thing. Meaning I had to unwind the coiler and reset the screws in the stop position. Not easy to do, but fortunately I had an extra BOA tool that allowed me to pull it off.
Second, when you are coiling the laces make sure to hold them down tight so that they coil in the most efficient pattern. Just makes it easier.
Even with my little mistakes it took me way less than 30 minutes to change out the cable and should have taken me less than ten minutes. Re-threading the laces was super easy to do.
I'd say if you are planning on a big trip, just get a set of replacement laces and if your BOA has the coiler make sure you have two BOA tools just in case you screw the pooch like I did...
