I have compiled a lot of info & testing on small coils but one question comes to mind & I have never had the opportunity to test this.----Would there be any (appreciable) difference (when working trash) in the operation/performance of a (standard) T2 with the 5" DD coil as opposed to the F-75 LTD with 5" DD (and operateing in the DE mode on the 75)?---------Thanks, Del
