Be it so, a ribbon on a stick is sure better than nothing.
But windflags are not really that expensive. And, unlike powder, primers, bullets, and even barrels, they do not dissappear with each shot. I have had the same set of flags, (my own), for the past 10 years.
Go to the section on windflags back on the home page. While I prefer a single vane, a daisy, and sail tails, matches are won with just about every design you will see. I would avoid designs that tend to be too ragile, or are not easy to break down and store. Remember, you will be tossing these in the back of the truck, or in the trunk, more times than not.,
As for how many. I set five at 100 yards, more or less evenly spaced, the first about 15 yards out. At 200, I use six, just spread out more. In all honesty, any more is too much for my limited brain power to digest...........jackie
