I find the thinner platforms (predator, seeker) are the worst offenders for squeaking. I think it’s the thinner stock causing flex combined with colder temps. My thiccc Trophyline Mission is like, negative noisy, but my predator starts squeaking as soon as temps drop below 50. Every video I watch with the seeker involves squeaking and flexing. It’s the main reason I haven’t added it to my Xmas list.
As far as quieting it, paracord wrap, stealth strips. But that kinda defeats the advantages of a thinner lighter platform.
