Undertaker choke question

[bigquacks]

I shoot a 870 with a 26" barrel. I have several choke tubes for the gun but will try to turkey hunt with the Undertaker .665. My problem is
with a new job and the fact it snowed here today, I haven't had a chance to pattern it yet. I am looking at shooting it Friday. I have a box of 3" LB #6
I am looking to pattern with. Should I take my other chokes just in case the combo isn't what I want? Also does anyone have experience with this setup.
