I am about ready to flash something. I was sorta happy with stock 6.5 and the overclocking, but the sucker crashes hard every few days now. I understand this is probably the build of the OS.

Which one is the safest/most reliable, and can be overclocked? I do not need anything special.

Also, I assume you can go back to the stock ROM if it does not work out? I would not want to brick the phone... most of the instructions look pretty intimidating, even for someone with decades of experience programming.
