A few months ago I sold my original Cibola and really missed it, so recently I purchased another one. I have only run the stock coils on the Tesoros that I have owned, but I was wondering what is a good additional coil to have on hand. I would probably lean toward a widescan coil. Does it make much of a difference in depth to go with a 5.75" widescan verses a larger one? What coils do you all like to use, and why? Thanks.
