Ferrule Tite or Epoxy will work fine. Be sure to clean adapters and inside of heads with Iso alcohol first.
Allan, there is no "best" for everyone, but I would strive for some balance for best results IMO. I would use a medium weight adapter and a medium weight broadhead over an extra heavy adapter and lightweight broadhead for example. I'd also not likely use a El Grande 190 and a 25 grain adapter either, I'd be more inclined to use a 150 and a 75 grain adapter if you get my meaning.
