I have a comp tip. So far, no issues. Keep the main tight enough to act as a backstay. When the pole broke, I had someone else driving while I played the spin. I wanted to see how high we could run it. I was watching the side shroud telltale and then telling him to go up a few more degrees. When I looked at the pole, it was bending up at a serious angle. I looked up at the mast, and the comp tip was bending to the rear, also at a serious angle. Then the pole snapped.
On reflection, I think the guy driving kept sheeting the main in way too hard each time we heated up a few more degrees until something gave. I think everything will be fine with reasonable sheeting. The guy driving is a big boy and easily exceeded the rig's limits.
You can find diagrams on where to attach the hoist. It doesn't go to the top.
