You can get flat top AW batteries now, that is what I am replacing all of mine with, I got sick of nearly new batteries with cracked and chipped wraps.
I don't recommend the Saucecode coils at all, I didn't have any luck with them at all but am enjoying my Saucecode with Atlantis coils.
Oh and for your question about temp control, it's ok but I rarely use it, just because a mod has temp control doesn't mean you can't use and enjoy it in watt mode.

Temp control coils don't seem to last very long, and on that note the Crown coils last nearly forever, my first one lasted 4 months with heavy daily use.
