The only Scotty Rod Holder I would trust with expensive top end gear is the later model Striker, The one where the base pin is reinforced with a stainless rod, not the earlier model that is hollow with no stainless rod inside it. All my other Scotty rod holders are used only with the cheaper gear, (Shimano 4000's etc. - the stuff I don't sweat if the base pin mount breaks off and the rod and reel go overboard). In my experience, because of the length (extra leverage) the Scotty rocket launcher type rod holders break off more than their others.
I have replaced the boom mounted tube type rod holders that came with my High Speed Riggers with very high end, high quality, solid, extra heavy duty all stainless rod holders. They are very expensive ($110 plus tax each) and they have to be modified by being drilled and tapped and a recessed set bolt installed. One of my fishing buddies is a good machinist, so that was no problem. They install with four heavy duty Allen Head bolts plus the set bolt so they can't turn on the boom no matter how much force is applied and they come with a special tool to adjust the ratchet angle. I am pretty confident I would break the Scotty Rigger mounts off or tear a fair bit of fiberglass out of the side of the boat before one of these rod holders would break and deep six the gear.
Keep in mind they are heavier than plastic and add a little weight to the rigger.
