I wore Burton speed-lace last year and Ride speed-lace this year, fucking love them both! I tried on a bunch of BOA this year and they just never felt right to me. The speed-lace is fast as hell and you can get them super tight or leave them loose. I love them, and am sold for life.
I like BOA, but I wouldn't recommend BOA boots with the metal cable exposed on top of the boot. I broke 2 cables last year because of my board edges and such. The do have warranty on them however. I now ride DC Gizmo's with half BOA, half laces and my boots are so comfy. They have a cover over the top of the boot so only about an inch of cable is shown on the side of the boot. Recommend
I have Burton speedlaces on my last three pair of boots (2009 Serows, 2011 Driver X, and now 2010 Driver X).
I have about 75 days on my current pair and have no issues with the lacing system. Love it. I do the lower zone up a little loose and the uppers fairly tight. I like that if I need a mid-day adjustment I can usually do it without even removing my front foot from the binding.
