Thank you for the wonderful information as this is something i to was wondering about as i am looking at getting started with the rebuildable thing.
its no issue, rebuildables are fun
as i've stated a few times in other threads, i've tried just about all types, so far though the penelope is my favorite, although the price point on penny is a bit high for the beginner, especially if you've never rebuilt one before...the vivi nova is a great intro though, and gets you used to making coils...i generally recommend cotton 99% of the time though, as i find its the easiest to work for, safer than silica, and i find the taste superior to silica, however the mesh wicks do have amazing flavor, they just don't work as well/easily in my setups.
