I have tried most options. The AFW 13lb Micro Supreme Wire is the best. It is quite fine and will fit the hook eye of most wire hooks. For example I use it easily with size 6 Clouser leeches. It is much easier to work with than heavy fluoro. The surflon spools are very small compared to a big spool of heavy fluoro so it is no big deal to take some along in a shirt/PFD pocket. I think that one spool of Micro-Supreme lasts a full week of popper fishing in June for me. I take extra because I have cheap friends who "borrow" my wire.
I use the 13-lb wire fishing for pike and have caught pike put to 40 inches without any break offs. I also use it fishing for smallies when pike are around to prevent bite-offs. It is not heavy enough to sink poppers so you can fish slowly. I prefer the brown or camo color to the silver. It will tear up most standard nippers - I use fishing pliers. My friend uses nippers though. You would need to verify with your gear. I use an 8-wt rod with 10-lb Rio bass leaders + the wire tippet.
As for knots, it ties easily. You could attach it to the leader with a loop knot (e.g. perfection loop) but I prefer a double-uni with 5-6 wraps of the wire. For tying on the hook, a loop knot is a huge improvement over the clinch knots. You will get better action on poppers and subsurface streamers. It is well worth spending some time this winter learning that knot.
This is a good video although I tie mine slightly differently:
