1. that gin pole is a "long slender column" ...needs to be supported in several places along it's length or it will buckle under compressive load
2. always use a torque wrench ( click style is best) for all the cable clamps (rope clips) and three tweaks ...first, second, back to first ...too easy to tighten one side and the other can come off with your fingers
3. "South West's tiltup kit for the Whisper 100 or 200 it is a 80 ft tower with 2 1/2 sched 40 pipe I noticed they have 5 guy wire sets" and I have seen three of their setups and none use turnbuckles ...I like 1/2x6 jaw+ eye

check out malleable wire rope clips and HD thimbles too ...if someone has a better deal, then let me know about it
