15.5x13.3 CoRe coil

I truly apologize if this had been covered already, BUT has anyone tested this coil on either the CoRe or the Racer yet? And how if compares to the stock coils in depth/discrimination/iron infested, etc, in the ground (real usage and results)? And if so, what is the pro/con to the standard stock coil? ANY BENEFITS TO THIS LARGER COIL? :-)

Thanks again brothers,
Bubba

Unbalances the Core and offers very minimal depth gain on the small coins (hammered) that i hunt for im sure it will offer more benefits to relic hunters or larger targets.
