Go with homelink. It's proven. When you buy the fuse adapter, it gives you all the mini blade fuses you will need. Use one to replace the homelink fuse, and a new one, whatever number you choose, to protect the v1. IIRC, the v1 hardwire has another fuse in it anyhow, so what number you choose should be the roughly the same. Lower, you might pop them often, higher you're not really accomplishing anything. Which is okay too I guess.
Did I confuse you more now??
