Can't go wrong with the H-Rail rod holder (part # 72020098), and for heavy duty trolling you can purchase the HD Strap kit for reinforcement of the rod holder's position (part # 72020099). One of the great things about this accessory is it's full range of adjustability: rotating and locking reel seat, tilt forward/aft and inboard/outboard, removable gimbal pin.

I use a pair of these. One paired with a scotty downrigger. Easy to adjust if I am not using the downrigger yet still trolling as I angle the holder more horizontal and towards the rear of the kayak. Trolling with the downrigger I elevate the hold and have it parallel with the downrigger boom. I've stuff al measure of rods/reels into these, Work great. I've got some videos in the pictures forum you can see how mine are set up.
