Nick, as long as you are getting sufficient coverage in both growing systems I would personally find it easier to mix up two different tanks with different quantities of material rather than mess with swapping nozzles.

So when you guys use the spray controllers do you try to maintain the same GPA across all blocks? Seems like if you don't have one (like me) and you mix a tank to apply across multiple training styles with varying row spacing the pesticide rate per acre would be out of whack between them. Here's my scenario. 1.5 acres is conventional free standing and 1.5 is tall spindle. When I did TRV calculations last season and checked the GPM of sprayer nozzles obviously with the difference in row spacing the rate was way higher for the tall spindle block. When I adjusted the gear speed so the GPA would match the free standing block, tractor speed was way too fast ~4 MPH. I suppose I could get another set of smaller nozzles for the tall spindle block to try to keep things even between blocks. Any further advise?
