I didn’t want to add a bunch of weight to my Polaris rattle trap so I bought ear plugs. As for the heat issues I wear “T” shirts in the summer. Whatever…
The biggest source of heat coming in for me in the pro r is the gap for the shifter rod to move back and forth. Do you have a link to where you picked up your insulation you ended up using?
I found it on Amazon I think I may try the siless 157 mil 2 in 1 since I’m going more for heat than sound. Looks like the hybrid is more for sound but that’s what you were going for.
