I would keep that bow if it were I, you could always ship your bow to get tuned, where there’s a will there’s a way. Unless you’re a dude who has to have a new bow every year, Levi Morgan got 3rd in National Level ASA event with that bow, just saying.
I would lighten it up unless you’re Levi Morgan at judging distances why take the risk? You could go down to 460, tighten up those pin gaps and flatten out your trajectory.
I wouldn’t buy a MBG that didn’t have micro wind, micro elevation and micro pins. I had the mountain lite and currently have the Pro Sight, world of difference with the pro pins and micro adjustments.
