Larger rolling aprons give more flexibility when joint rolling. With practice a variety of sizes can be rolled with the larger machines, which I find gives more flexability than with the small standard sized rollers.
The Elements papers are thin, and the glue holds well without being overwhelming. The 300 packs are generally cheaper per sheet than the smaller sizes, although the glued edge may curl a bit. Keep dry.
I'm not picky about specifics on rolling tips (crutches). If none are handy you can get about five out of a regular business card with a pair of scissors.
