Thomas, Robbin, and quality M-folks, I have used the Loos gauges to measure shroud and stay tension on both my M17 and M23. I thought I was doing everything correctly with German precision until I read a report that most of those measurement tools are fairly inaccurate. I would set tension at 10% of breaking strength (as per instructions). It always seemed to me that the rig was too tight. Well, my new formula is to set tension by feel. I do still use the gauges to balance shrouds side to side, bit I am definitely tuning my rig softer. It fits in with my easy going, relaxed, don't rush me state of mind. As always, I'll watch the rig under sail. I'll be checking the slack of the inner shrouds under a hard beat to weather. Adjust as necessary, and check again after several times out. Now, if I could only measure voltage and current by feeling a conductor!!! It would lighten my tool bag on service calls.
