I have done the tack-wires-on method many times too. A few nodes is easy to handle, with leads held safely with tape to keep from shorting. When there are lots, I usually use some kind of connector like a square pin header or plug at the ends to keep them all together and safer and organized. Then probe each with a test lead including a pin or socket that can stay connected if needed.

I happen to have in my pile of test leads the longest grabber hook I've ever seen, and I'd think even longer might be available. I got it decades ago along with other junk, and never knew who made it until just looking now. This one is around five inches from the finger hold to tip, labelled "maxi grabber." I looked up that name, and it seems to be a Pomona product - you'll see all sorts of hits with that. I think this is their model 4225-2, where the "2" is probably the code for red.

I've actually seldom used it except on bigger old-school circuitry. Even with longer reach, there are still the problems of manipulation to grab something, and visibility, so you'd still likely have to tack on some kind of node extensions to probe say in a card cage. It's also kind of fat, but good and strong - maybe there are skinnier, lower profile types too.
