Catrin probably your comment that wired or wireless, things like a nudged sensor can impair accuracy was really a helpful comment. I really wondered about that--did one over the other reduce that?

Nybiker, your links are very helpful but following the link on the Node 1 you see this:

"Node computers DO NOT INCLUDE speed sensors. An ANT+ speed sensor or combo sensor needs to be purchased separately to complete the kit
Node 1 can expand to add cadence and heart rate with optional ANT+ sensors."

I think that is what he was referring to. It is also helpful to hear that this may be peculiar to the Borntrager.

But if I go with a wired Trip 3 and decide to upgrade to a wireless when I have a better idea of what I want, cost wise that's the pill I'm thinking about swallowing.

It was "karmic" that they didn't have a Trip 3 in and so no big deal. I have some time to decide.

I am also interested in knowing more about the Duo Trap feature which is, I believe, an aspect of my bike.

This is all very helpful.
