The RX1 is single sear and uses both a magnet and a spring. It has a bit of trigger travel but not bad.
The Lucky is a dual sear and is all magnetic. It has virtually no detectable trigger travel. The Lucky's hook to trigger distance is also about 1/4" longer than the RX1.
They are both good releases but I (for my style) would like to see more weight for the trigger pull (4 to 5 lbs). I get a reading of about 2.6 lbs on the Lucky and the Rx1 is pretty close with a modified spring. I would also like to see more hook to trigger distance. One drawback with magnets is that they will pick up tiny magnetic particles and need to be cleaned periodically. I'm not sure where those particles come from but they are a real pain to remove.
Another release I use is the single sear Loesch Jackrabbit. It's very similar to both of the above but with out the magnets. It can get higher trigger pull rates but after 3 lbs the hook can be a little tough to set.
