This, run through a Lockjack, produces virtually no friction. I can easily tell the difference between using it and using a friction saver.
Kill the friction, save the climber.

Friction is everything, D Mc. My point was 2:1 being more motion overall, regardless of friction. 1:1, half the motions, no movement or friction of the rope at the tie-in point, at any time, just rope pressure created by your weight .
In 1:1 ascent, none of this advanced climbing gear is needed for advantage over friction. Friction is not an issue, at the crotch anyway. 1:1 friction comes at the dual ascender, and it is minimal, almost negligible friction going up.
On descent, friction is your friend, and how it is managed, (2:1 or 1:1) is your force against gravity.
I only mention this because the advantage to using ANY friction saving device is for 2:1 systems alone, not 1:1. I'll shut up now.
