I'm currently using bags from midtown comics that measure 6 7/8' X 10.5' and boards that measure 6 3/4' X 10.5'.  I would like to have boards that fill the whole bag, but when I bought silver age boards, assuming they would fit, they were slightly too large.  Are there any boards that will fully fill current size 6 7/8 wide bags?

it depends on what brand bags and or boards you get. i know that at the shop i used to work at we sold some that fit real snug but not too tight. but i can't remember the brand. 

anyone?

They should be labeled separately: Silver Age and Current (or Modern). The current size boards measure 6-3/4 x 10-1/2, like you said. I don't know what you mean by 'fill the whole bag.' Mine fit pretty snug.
