"and i use a 200ft rope on every pick. guarantee your game is not anywhere near as productive regardless how short your rope is."
Sorry to burst your bubble "oldirty" but "my game" is just as productive as yours, I don't need to see your operations to know this. This isn't a contest, it's a forum, keep your assumptions to yourself - thanks.
Like Crazy Jimmy said, "enough rope to get to the ground at all times." I totally agree with that statement.
I personally don't climb on any ropes shorter than 80', and that's a rarity. I also climb on a 120 safety blue, a 150' imori, and two 200's, HTP red and a Lava. I am no stranger to long ropes, cranes or not. I _usually_ climb on a 200' rope.
Yes, your rope should get you to the ground, no matter where you are in the tree. I won't question that.
A typical crane job for me is a 100' white oak, 40" diameter, dead as a doornail, over a house or other target. Wide-open grown, so 100' is to the tips. Setting the slings from the crane - if I get injured, the crane lowers me down at this point.
Do I make my cut at 100'? No, I probably am going to drop down about 30' to cut. I probably didn't rig it at the tips, either. So if I get hurt, my 150' will be long enough. When I'm down to the spar, doing the last few multi-thousand pound picks, I sometimes need to move around the spar without moving the whole 200' that's balled on the ground (i already had to deploy the pack) in a mess of poison ivy - nor do I need my crew to do that for me if my rope isn't unnecessarily long.
As I go through the tree, I may even switch ropes. This is easy to do with a good ground crew, especially with backpack ropes (i have two of these).
More tools in the box. Not one rope for all jobs. I think a lot about what tools get me through the job most efficiently.
