I don't use the extension myself (only 175 lbs) but when i lightly flex the header WITHOUT the extension, there is very little play because there is only 1 connection point. WITH the extension, of course there is a more play because of 2 connection points.
If you're concerned, you can go to quest outfitters, order 2 26 inch poles, then cut them down, using a pipe cutter, so you can have the same length (39.5) header, but with only one connection. Probably much less play.
Or maybe even order the thicker .742 poles, I think the ones supplies are .625.
I have 2 RRs, one with net the other without. I love them both and will reorder them in a second if they ever wear out. I will never sell them, and recommend them to anyone with out question.
