Lots of good advise here.

Don't forget to bring patience of biblical proportions, an undying will for perfection, and the ability to find joy in taking things apart, and putting them back together, endless times. lol.

Seriously, if you're pulling a good gear out. Keep every piece of it together as a setup. Same spool, or carrier, bearings, shims whatever. Then if you ever want to return to that ratio/set up, it's a bolt it in, no setup required, and go cat go.

Like Jbody said,,side adjusters are just too cool for words.
