To get more purchase with the GRCS the end of the rigging line can be used to achieve extra mechanical advantage. By placing a pulley on the said piece and running the tail away and cinching it off ( I presume next to the last pulley).

Christ man...if you are winding them up that tight somethin's gotta go let go!!!!!?

it is not quite zero but close to it as the piece hangs from the pulley.

 

12.5* prob?

Uh-huh, I getcha... That wouldn't be static though would it?? If it was static you'd never lower it to the ground...

I'm following a chart....12.5 - 0 seems to make little odds.

 

 

0 degrees 2x

20 degrees 1.97x

30 degrees 1.93x

45 degrees 1.84x

60 degrees 1.73x

70 degrees 1.64x

80 degrees 1.53x

90 degrees 1.41x

120 degrees 1x

I meant that the GRCS would be winching up, so no additional weight would be added into the system as it breaks its hinge, as opposed to dynamic rigging. Once the piece has been cut....it gets lowered.

What do you mean? A piece of the tree or rigging gear?

The tree is the UNKNOWN QUANTITY. I'm trying to get my head around the extent of 'abuse' that my rigging gear can take and how to use the tree to my advantage.

Ok, but I suppose that there are implications for the load placed on the anchor limb. Regardless how the load is transferred above the piece to be lowered, the angle is tightest at that point, near 180 as it comes down???
