1. Kite: (7) r2c2 = r2c9 - r1c7 = r5c7 => - 7 r5c2.

2. Kite: (9) r1c3 = r5c3 - r4c1 = r4c5 => - 9 r1c5.

3. Discontinuous Loop : 9 r1c4 - (9=7) r1c3 - r2c2 = (7-9) r2c9 = r2c45 - r1c4 => - 9 r1c4

4. Double Kite Loop :

(2) r2c4 = r6c4 - r4c6 = (2-9) r4c1 = r4c5 - r5c4 = (9) r2c4 loop => - 16 r2c4, - 467 r4c1; lclste (just one pointing pair).

PS - Just tried this in Hodoku and their solution was exactly the same. Is this a case of Great minds think alike, or All fools are cut from the same cloth. Probably both. Looks like we both should go and fly a Kite
