I heard not to use synthetics because rotaries are oil injected and synthetics don't fully combust.

The argument goes both ways. If your rotary has been running smooth with mineral-based oil, then there isn't a real, outstanding point for you to change to synthetics. However, turbos have generally shown good response to synthetic oils.
I've used Redline and Mobil 1 with good results. The Mobil 1 synthetic seems to be less viscous, and my oil pressure was always low (around 15). I switched back to Redline and the oil pressure is almost always at 30; except when the engine is really warm (then if falls to around 15). Maybe coincidence ... I dunno, but I'm happier with the Redline performance. It's worth the extra $3 a quart, IMO.
MaxCooper has had good results with the Royal Purple as well.
In Texas, I run well with 10W-30; or 30WT (Redline) ... they're pretty much the same thing. For colder climates, I would think you would want to run like a 20W-50.

You have it the other way around.
