Northwest Fishing Reports

Hi All! Looking for advice on what sizes of traxtech people are running? We have 2018 Hewescraft 200 Pro V ET soft top, didn't get factory downrigger bracket/stern rail. Want to run our Scotty 2106 HPs on traxtech plus 2 additional rod holders. Any advice on which mount people like for these downriggers? Also want to run maybe a 4' section of traxtech across the transom above the access panels. Also any installation advice would be great. This boat may see salt water but not anytime soon.
Thanks so much!
