gonna ride the small stuff till I can get a spot on the roof to rappel to after the cut
wont be riding anything over 30% capacity for the crane, tied in above the ball, once we are on bigger stuff I will rappel to the roof, pull my line off the crane, and be 100% free of the crane while he sets the wood down, once we are on the spar and free from the house I will most likely just spike the stem
I'd strongly advise you not to ride any picks whatsoever. You're good to tie in above the ball with an ANSI approved crane tie in point like this to lift you into position (even though many crane ops wont allow this). However, the idea of riding a pick after the cut is extremely hazardous. I'm not so concerned about your body weight maxing out the crane load. The concern is how a pick may behave after it's cut. Especially with an inexperienced climber, picks can severely jolt around- or tip upside-down if the weight is not distributed correctly. There is a high potential for injury or worse. There are many things that can go wrong in this scenario. PLEASE reconsider this job. This is not a good "first" crane job.
I'm honest in saying it's very impressive what you've been able to do at your age. You don't need to do this to prove yourself. Please take time to listen to what the guys (and gals?) on this forum have to say before you get hurt.
