I did a couple of the inlines but stopped, they had a tendency to leak and cause problems, started going directly to the mother boards.I'm not sure if I would go with the inline connector for changing coils, if it was wet/drysand no problem but I'm not sure about use in the saltwater. Maybe someone can chime in on that.
Over the years I did try several, never had any luck with the inline, and that includes the Coiltech one. I did finally make up one that worked very good that was made into the endcap.. but I found the best setup was hard wired for me.
Maybe someone else has there setup, with the inline connector for changing coils and can give feed back.... Now the CTX / headphone one works beautiful.
