Thanks and I agree but I don't think everyone does.I did not mean to not use flags at 600. I meant that if you see the flags in an opportune position, get the shots down range as fast as possible.
The bottom line is, at 100 and 200, and maybe 300, you can hunt and pick a condition, because a good flag reader can be extremely precision in his abilities.
If you try to hunt and pick conditions at 600+, you will probably end up with groups that are not very competitive.
