Hi Tuna,
Penny and I use Wick's flags that are starting to show their age. Just like me I guess.
We set out five flags along with a WindProbe. We space the flags slightly closer near the bench and slightly further apart near the target. We place the probes about one third off the way downrange fron the bench. Most of our flags have props.
A little story about whirligigs Vs no whirligigs. Several years ago I removed all the props from my flags. I found I was fixated on the props and not paying enough attention to the tails. Well, this was fine untill we got a very rainy day. The breeze was light. My flags without props told me exactly nothing. The tails just hung there like a...limp...well you know what. The guys on both sides of me had props on their flags and they were getting the info they needed. So when I got home I put my props back on. One should pay a lot of attention to those tails. By-the-way, the probe becomes next to usless in the rain and in very light conditions.
No, I do not use the bobbing flags, just to much for this ol' boy to absorb.
