quote]i produce nice safe work everyday. i have been rigging cranes since i was 16; for the record i'll be thirty five in september. All types of rigging demo and installation. they are all the same: know you boundaries and work within them. spider legs if you need them, two strap if you need to, controlled felling if you need to, single leg pics if you need to, whole tree removal one shot if its plausible and you have the lay down room sounds great. remove a twenty thousand pound leader or section of trunk; better hope you know how to crib a crane so the out riggers don't punch through the street. personally i like single leg picks and tip tying them so they are easier on the ground crew to chip and i like one sling on trunk sections rigged to tilt over so they land easily but i know how to use a wedge so i don't worry about a piece rolling around slowly have been known to hang a leader off itself then pick it with the crane when working with a bucket & a crane.

Bottom line is the old adage "practice makes perfect". Pro golfers go out with their lunch pales and hit balls on the practice range for 8 hours a day every day until their hands bleed in some instances. A pro is a pro in any profession.
If you don't have a crane, get one, even a starter one. Once you have one, use it daily if possible, even if the job doesn't entirely call for it. Op practices, climber practices, gm's practice. Procedure is followed and eventually set in stone with ANSI in mind. Questionable circumstances become fewer and farther between in appearance as years pass.
