Don't you use 1122s? I don't think you mentioned what you actually use.
The performance on different years of the 0-27 line vary somewhat as well.
The whole lot of comments is aimed at full O turnouts or other things you don't have because you didn't mention what you use.
Besides, different locos will handle type X turnouts differently. There is no one cure all/without quirks or dead spots for every loco.
You may want to jump center rail power into the ends of the center turnout; if you'll recall the Lionel suggestion to use a drop on each turnout leg, rather than drawing power thru those.
If anything, a little speed can usually help an engine make it across a fussy turnout's connections.
Slow antiderail is something you deal with as is, or mod for constant power on 0-27 turnouts.
