I‘ve looked online and have got many many different answers. The most common answer is that one is shinier/cleaner and the other is duller. What is true?
#1 is just the pure shiny copper. Wires stripped and no casings. #2 is copper wires that have had the casings burnt off. This makes the copper look Black from the heat. Of course, you get more money with #1!!
Rule of thumb. #2 is smaller that #2 pencil lead commonly #10AWG Stranded and #14 solid and smaller. Therefore #12AWG SOILD wire is #1 wire and stranded wire with strands about the size of #12AWG is considered #1. Here's a hint for those of u recycling wire. Do not burn #2. You will lose too much. Furthermore always wise to strip #2 wire (or burn if u dare) but if you have bologna cable then let the mess with it. You end up making out just as well b/c the labor spent far outweighs the deduction. You end up making out better. PS I have recycled copper wire for years as a comm and industrial wireman and prev. apprentice.

For a first time track rider, I would bet you'll feel more comfortable on a skinnier tire Less work for you. That 200 rear would be a BEAST to handle if you are going to any technical type track I went from a 170 rear to a 160 rear on my old track beater (95 ZX-6R) and even that small change helped my confidence immeasurably
Wow, you can fit between a 180 series and 200 series on your rim? I'm a little jealous Regardless, the wider the tire profile, the slower your turn in is going to be; you're going to have to work harder to get the bike over. If your track experience is limited just non existant, than I'd learn your limits on your stock tire size first; chances of you using your rubber to its fullest extent are going to be slim, for the first bit anyway. I think, after you get a good feel for what you're on, then you'll know if you want more rubber beneath you. I'm too lazy to find the source, but a wider patch with proper air pressure will give you a faster straight line speed potential, but as I said before, you're going to have to give a bit more effort to get the bike over in its corners.
