I have a Tacx wheel-on smart trainer. Works well with Zwift. Zwift will save your indoor rides to Garmin Express, Strava, etc automatically once you connect the apps, so you really don't even need your 530. The only potential issue I can see with your projector setup and 150" screen (I envy you) would be placement of the projector. Can't have it behind you, or all you'll see is your own shadow on the screen. Ceiling mount?
