Interesting compensation with shortening the pole. Did you shorten it to right at 105% of J or to just under 110% (the class pole is just slightly over 110% but maybe the handicappers round down?). I'm going to check with PHRF to see if they'll give me any credit for using a J-24 pole (9.65 ft long = 107% of J)...probably not...

Also: did you use a small reacher at the mast's head or fractional?
