Great tool, use it safely
Shooting a biner up into a twiggy tree is a quick way to get it snagged.
You say this with such authority as to make it sound like you know this from experience.
The reason I use, not
any cheesy small biner, but rather a Black Diamond micron, the smaller of the two sizes, is that it has such a strong spring gate that it
doesn't open when dragged across the unavoidable twigs in a twiggy tree. That's why I've been very specific about this piece and have given reasons for its merit.
All my ropes have spliced eyes, making the offing of the bag and the onning of the rope an instant maneuver. I focus on the parts of my job that are repetitive in nature and look for ways to boil these tasks down so I can focus more on tree care rather than futzing with gear.
If my ropes didn't have spliced eyes, my method would be bunk, and I'd go to taking off my gloves and tying and untying little knots.
I rarely get the shotbag hung up in a tree. The times I do are when I fire through a tight, vertical v-crotch, or if the bag and line wrap around the limb more than one full revolution. Occasionally the line gets caught under a piece of bark These hangups, however, have nothing to do with the biner.
Listen to rbtree! This stuff HAS happened and stitches in the face, or dameged eyes are never a good thing. Think about this the next time you fire one off 'shotgun' style -TM-
