I just went through vetting this coil for use with my V3, one it is heavy, two it is not V rated and that causes some instability when using all three freq. or 22.5 specifically. I checked with White and they say as was pointed out in this string that White is not going to V rate this coil because the D2 is as good or better and half the weight. I did work with the coil for a few days and it seemed to not have any real advantage in pattern or depth, but it sure was heavy! I am returning this coil today to KellyCo and swapping it for a White 5.3 & something else that I haven't figured out.
