I use a Jacktite pole as we speak. The 31 foot version in black.
It was my primary support from 2k7 to 2013. At first it was the center for a G5RV Jr., then I cut off the coax connector and just run the 300 ohm to a 4:1 just outside the window. Now I call it a 52 foot doublet.
It's survived 40 mph winds w/ one support at the roofline. No guys either. Never balked, never had an issue. Now it holds up the far end of my Par End Fed SWL strapped to a tree. For me, its been worth the 70 dollar investment.
I've also used that military 4 foot section stuff for a 'loaded' 80m antenna w/ a couple of coils on each end. There is some weight to it. I used 6 sections anchored to a 2x4, again, no guys. Same winds, didn't fall nor balk, but kinda clumsy to setup for just one person. I'd be lying if I didn't say I dropped it 2 or 3 times before I got it anchored to the 2x4.
Having said that, I now have the 12 meter Spiderpole for the doublet. Just my opinion, if you have the extra coin, drop the 120 for the Spiderpole. Either will work, but after having tried a few solutions , the Spiderpole has worked out best for me. YMMV.
