I have 2 coils that fit both the DeLeon and the Golden. I have always used the stock coil. The other is the 8" round Donut coil. My question is this. Would I gain anything by running this on either unit? I am not familiar with the coil. I just got it. I was thinking about putting it on one or the other MD and leave it a while. Is this a good coil to run? Thanks Beale.
