I have an Echo Ion XL 690. I don’t fish the sound as much as I should, but have hooked up on sea runs most of the time I go out.
I have’t handled a lot of “saltwater” fly rods, and think the Ion XL has a fairly large grip; the top and bottom of the grip is fairly pronounced, compared to other rods’ grips, e.g. Sage Maverick, etc.
The Ion XL is pretty quick, but not super fast, and does feel like it has a stiffer butt. With enough line out, the rod does load nicely in the mid-tip sections. I primarily use a sinking and intermediate lines. Haven’t found a floating line I love on the rod yet. Ditto on the durability of the rod.
Not sure where you’re located, but if you wanna borrow the rod for a few outings, let me know! I have a beater Sage Fli as a backup.
