+1 on the easy Brackets!
On my Speedy I had a Slipstream Viper screen. It was pretty good & reasonable.
You can definitely rack up some miles on a vertical twin. Get a touring saddle, sissy bar & luggage rack and you're good to go. FYI you'll be running at around 5,000 RPM at at 75-80 MPH but if you're OK with that the bike is fine. I found the high RPMs kind of wear on you but give it a shot. Good luck & ride safe.
