We decided to scrap the cross brace at this point - after deciding that it was our main problem, and ripped it open with a "sawsall".

After doing so, we tested it out again, and got AWESOME results! Then we switched to a fiberglass arm, and got even better results! (if you're using a fiberglass pole, a bunch of tape works really well as the ammo holder.)

Although, we had to make some adjustments.

We were kind of worried about drilling into the new fiberglass pole, so instead of putting all of those bolts through it, we just used some rope to make loops. The surgical tubing was content without having something to keep it where we wanted it, so we didn't even bother making a restraint for that.

We added a 12' 4x4 across the bottom back of the posts, and then a diagonal support from the end of the 12' "back brace" to the tops of the posts. Simple enough, and strong enough to take one hell of a beating.

Well - that's it!

ENJOY!
