   Personally, I'd go with blocking.  It's stronger and easier to install, especially since you have a ceiling under this.  Cut it carefully to fit nice and snug.

   I wouldn't put it in unless the floor is springy - Bridging or blocking might help that.

   With a 23' span you're likely to have problems unless your floor system is about 16" deep.

   According to a recent survey, men say the first thing they notice about a woman is their eyes.
   And women say the first thing they notice about men is they're a bunch of liars.

   I'm with Boss. Use plenty of adhesive when you're putting down the subfloor. Screw the bejeezuz out of it, less impact on the plaster ceiling. Crimoney, 23' span, what size are those LVL's?

   Billy, I had to go with 12" LVL's that are sistered on existing 3x12's.   The house is a ranch nothing in the atic.  I going to put in blocking while I have the floor open, sounds like it can't hurt.  Thanks for the advice -Ed
