The SE is identical to your SMR in seat/tank/ergos for both you and passenger. Spend another $50 and add a SD Touring screen to the headlight shell. It makes all the difference. I still have my SE after selling my SMR, without the little screen you feel everything. The Adv is not as good on road as the SMR and the only thing it does better than a SE IMO is carry 2 up.
I used SS bolts to add the screen. Simple task, 4 holes IIRC. Or add yourself to the list of riders who hate the Adv screen and can't find a solution to the buffeting!
I found a "tall" flat Renazco really helps the comfort for both you and passenger, and tell them you are concerned about passenger comfort, I bet they have a few tricks for that too. If you think a tall, flat seat will make the bike too tall, forget the Adv or SE too!
And, add a shield to the downpipe exhaust if you want to explore a bit, easily dented.
