For Dick's you will need the 7 foot stand.
At this point all tapers have abandoned the OTS and moved FOB.
Bring your stand if you'd like, but also make sure you have the ability to clamp since not every FOB taper can run their own stand.
At this point I'm running just my 7 foot stand, and a superclamp/extension pole for any place I can clamp.
It should be noted that in many venues more non-taping fans have figured out that many "tapers sections" in venues are a great place to sit (good sound, good sightlines), so I will try to bring both stands. I have recently run into a few situations where I would like to clamp, but the people sitting in those seats aren't willing to move (which is fine), so I've had to move another row back where you can't clamp, and run a normal stand.
