OK let me clarify I haven't had any problem with an overly high DC.
I have had a problem with Low Rolls.

That isn't a Polearm nor does it have reach. But still an excellent suggestion.
You can get a lot of nice Weapons via Races. Half-Elves, Dwarves, even Elves.

Magus also comes with built in class abilities to boost concentration for casting defensively. Improved spell combat and greater spell combat. I would never suggest Combat casting or any other feat for this as they will become obsolete feats or circumstantial at best.
The other mechanic from spell combat along with improved/greater spell combat and true magus should be all you will need.
