I took a Diamana 70 from my 13.5 and installed it into a 19 (cutting the length by an inch). I notice the feel between the Diamana 70 is almost identical to that of an M60+ x5ct Lite. Did I inadvertently create a 70g a flex shaft for the 19? Reason I ask is there is no tipping on a 3 wood and about 1" for a 5 wood if you construct a shaft.

On the trackman, the M60+ (1/4" longer) was 10 yards more vs the Diamana 70. 204/184 vs 194/176 (total/carry). Swingweight should be identical (10g weight for the 70g shaft is 1 point; 1/4" length is 1.5 point).
