The ZEN is big and slower. For one who learned to fly on a REV 1.5, you will have a lot to get use to. I learned on a REV I, long before a REV 1.5 was available.
50# lines are too light for ZEN unless your into zero wind flying.
Line length for starters, use lines in the range of 80-100 ft. Later you can use the shorter lines with ease.
Experiment with different rods. The most beautiful rods are unquestionably the ZEN rods. However I prefer using in general the green race rods. Also the normal 3 wrap rod I find is quite nice.
For those of us who started on the Rev1 the Zen offers additional sail area and so further 'stability' and light wind viability but compared to the 1.5 sails the 'turning' speed is slow. The 1.5 flier is likely to pull the larger sail out of the air rather than 'wait' for the kite to complete the turn. The Decs preferred the larger sails in order to 'fill the sky' and so would often fly to the upper wind limits rather than taking the easier option of the smaller sail...
