Well, naturally, having your strip till rig and your planter the same width would be the easiest.  Next to that, having good RTK is important.  Man, I dont want to rag on you because it can be done....just really got to watch what you're doing!

Does your autosteer have tilt compensation?

My planter and strip till rig are the same width, and I still have hard enough time doing it right....guess it's just me, though...as I don't have a super-nice autosteer..
