I'll throw in another vote in for the BOA. Most importantly, you need a boot that fits and is comfortable regardless of the closure type. I find the ease of the BOA is great, though i would recommend a dual BOA. I have experienced when riding hard that a single BOA can cause the bottom (on your foot) to tighten from the pressure you put on the upper boot from flexing. This can happen with a lace, too, but is alleviated with the dual BOA because you can adjust leg and foot zone separately.
