I'm pondering a new type of multicender based on a principle different from what is currently available. I've never used a multicender, but it seems like desirable attributes include:
Reasonably small and light
Mid-line attachable with no disassembly
No potential for free fall
Easy tending during ascent and branch walks
Integral chest roller (device easily clips on/off a chest harness while climber is on the device)
Easy way to disable descent function (for safety while working)
Replaceable wear surfaces (at reasonable cost) or very long service life
Compatible with a variety of ropes without adjustment
Smooth operation on pitchy ropes
No or little sit back
Easily modulated descent speed
Suitable for SRS and MRS
Are their other attributes I've missed? How important is a swivel on the main connection? (I already know it should cost less than $20 and spit out a cheeseburger at lunch time!)
