Honestly, the OE hooks more than advertised. The Changeling did have a stronger backend, but similar length and reaction shape...I could easily play down-and-in or swing the lane with both. Long run, both are light-medium pearl balls, so I think they are similar regardless of core dynamics, but I'm sure stuff will differ...
But go with the FIFO method...the Changeling does have a better core in my opinion and hits like a tank, while the OE is more of a mixer, in my book!
