I just got a 5x10 and it works just fine, and I like the footprint a little better than the NEL sharpshooter. As for dept it is a little less on my air testing. Here is my testing results for all the coils I could get my hands on.
Please note that I added up the disc depth to get a score for each coil, and I didn't include AM numbers because I don't hunt in AM. Those numbers are at the right of the chart in the colored boxes.
Also note the top chart was using a clad quarter and the bottom one I was using a clad dime for a target.
Hope this helps,
