Just installed a Fishhawk X4D, so far so good. not bad to install just put some thought in triducer placement, and if possible run power cable direct to battery, Little tuff on wallet but well worth it.
Blacks for me too,just starting to have twisting problem right at release. I use the best swivels on the market, wondering if fleas may be problem, or possible double loop i like to use just before clipping line to release. Anybody ever see this?
