For rec climbing, I use up to three lanyards, sizes, 15', 30' & 55', depending on the tree and my climbing objectives. The 15' & 30' lanyards are used primarily in a MRS lanyard configuration connecting to my saddle's side Ds. The 55' and sometimes the 30' lanyard is used mainly as a secondary climbing system attached to my rope bridge's swivel, usually with a throwing hook or a self-mounted anchor point, so for that, I use the MadRock Safeguard, similar to the Petzl GriGri. Both the Safeguard and GriGri are mid-line attachable, so either one works well in an SRS or MRS lanyard configuration and a RAD setup. For my shorter primary lanyard, I use the Petzl Micrograb, which works great too for a side-Ds lanyard using a doubled rope configuration. I acknowledge the warnings about the fact that the Safeguard and GriGri can slip when unweighted, but that's just something I am mindful of and it's not a deal breaker. I'm also mindful about using my breaking hand, when adjusting the Safeguard or GriGri.
