Well, I got another compadre on the way, this one with the 7" concentric in nice shape. I really wanted it to try out that 7" concentric coil. I am trying to decide whether or not to wire in an 8" donut so I can have the 7" coil for use on my silver and outlaw or just leave it on the compadre. I have all the tools to do a good job with this just wondering where I would be best with the 7" coil. I have the 7" Widescan now and really like the size and solidness of that coil. Anyone have experience with the 7" concentric on either the silver umax or outlaw, also any 8" compadre users out there? I have a compadre with the 5.75 and like it.
