I guess it would be more important for the Jays offense to have the roof open more than anything else (although Dickey's HR numbers do seem to spike with the roof open, although that may coincide with the warmer weather as well.)
And for what it's worth (which probably isn't much), Pelfrey has a 5.88 ERA and 1.55 WHIP in 41.1 IP indoors.
