No, maybe I typed it wrong. You can put in what you want as long as it's Invector plus.
I meant you can't mix Invector chokes with Invector plus.
It would probably look odd if you had one flush, one extended but as long as you're aware and happy it's your choice.
I just bought what I wanted to match up in either flush or extended.
Thing is I tend to stick to the same 2 chokes all the time regardless of what I'm shooting.
Currently open and extra open both flush. But occasionally I swap to 1/4, 1/4 extended just to see if there's any difference. Rarely is.
