Riser geometry issue putting mini risers on large harness rings?

[FrogNog 1]

I searched and didn't find a definitive answer to this, just a note from Bill Booth that when he got back from his ski trip he would address it.

I hope he's back by now.
Question: what are the geometry or other implications of connecting mini-ring risers on regular-size harness rings?

And, as a followup question: are there any geometry or other implications of connecting two sets of mini-ring risers on regular-size harness rings, such as for an intentional cutaway canopy?

A mini ring riser on a large harness ring has a little less mechanical advantage than on a small harness ring because the lever arm is less due to the thickness of the large ring. It will work though. Two type 17 (1") mini ring risers in one large harness ring, is an easy way to attach an extra canopy for a breakaway rig. We've done it lots of times with no problem.

Do you run a separate set of cutaway cables for that, or use some sort of pins to hold the cloth loop?

I've done it both ways. Since the purpose is to simulate a breakaway, we usually hook the normal breakaway handle to the first main. We then use two short pieces of yellow cable, attached to two separate loops, which are velcroed up onto their own risers.

Any chance of a pic of this config Bill?

Is this basically a riser set with its own cutaway cables entirely self-contained? (And, obviously, one would have to release each side individually like capewells.)
