RE: Which is lighter CA or Titebond?
I use em all CA, epoxy, and Tight bond wood glues, it does seem like the CA is a bit lighter if you don't use some glue control when building.
a couple of ways I do this is I take a old CA bottle crack out any residue from the dried glue and fill it with Tite Bond with just a tiny bit of water,a few drops, to loosen up the glue, I use a new top and I have a glue bottle that I can really control the amount of adhesive I use, and where it goes
I can also make nice tight fillets when necessary, although I rarely add the excess glue, if the joints are tight its not needed only when I am in a hurry to get a section done or for jobs where CA is specifically indicated the fumes can be nasty they give me a headache if I use it too much
