The inside of the straight handleset runs into my deadbolt knob on the main door so both can't close all the way. Are any other handles compatible?

Unfortunately we do not have a smaller inside lever handle available for the QuickFit handle set. If the handles interfere with each other a couple of options to consider. One option is to add a shim to the front face of the mounting surface . This will move the door out away from your inner door. Another option (if the door isn't installed already) is to install the door with the handle on the opposite side.
