Just get a good one...I’ve had my 40 foot for 12 years.....keep an eye on rope as it’s easier to replace before it breaks ....cause then you’ll need a boom truck. Also...I suggest a pole with internal rope and not the traditional external cleat and a ball type pole topper so the flag won’t get caught. I’ve had better luck with oversized poly flags with reinforced end vs a nylon flag. I use a 10x19 on my 40 foot pole. Looks much nicer than a 10x15 plus allows for trimming and hemming to get more life from flag
obviously not the answer you were looking for....but my 2cents.
