I’m feel pretty much the same way as you Steve about the DCT, only I feel the same about CarPlay too.
Goldwing pillion comfort is another area that will be difficult to leave. The Goldwing is an extraordinary bike.
I’ve tested the NT1100 - very nice bike and it ticks the DCT and CarPlay boxes, but no compartment for your phone and a screen that’s not adjustable on the fly let it down. Should you ever test an NT then make sure you do without a top box as it reduces pillion room.
