Also, I like the durso pipe better.

If I were to go with a Durso design I would have been limited to a 1"
standpipe since fittings for any larger size pipe would not fit in the
overflow.

The thing is, that at your current flow you do not even need 1".
1" is needed for flow like 600-700 gph. You have about 300gph.
My Allglass 1" Durso, while "limiting you" to 1" would make it quiet
and still should perfectly handle the 300gph flow your pump makes.
