I'll tell you this much about the R70, and Brinks locks in general:
The R70 takes quite a bit of tension at the beginning to overcome the spring and pick it to a false set. Then you have at least 1 serrated spool pin to deal with. The serrated sppols act funny when you try to pick them and they take quite a bit of pick force to overcome the serration.
My point is this:
Once you get the lock picked into a false set you must identify the spool or spools that are hanging first, then when you try to set them they're going to hit the serration and feel as though they set when in reality you have to continue to press the pin until you feel it set yet again. This is where knowing the spools Brinks use are also serrated comes in handy.
These spools are also prone to hanging really hard, so you have to really control your tension when trying to pick it out of the false set state. If you're using too much tension you'll almost certainly "snap" the pins up into the chamber and overset it. The R70 has such a tight spring that controlling your tension can become quite a chore in itself.
