First, let me say I would kill to have your lifts. I'm 63, was progressing ok, but got two injuries. Yesterday was the first time in weeks I could Squat and empty bar without pain.
I know another lifter, who is also considerably younger, and he progress considerably better. He has now hit a point where it is all heavy, after a long run of reasonably easy progress.
If you want to be "strong"... 315, 350 and 370 on the squat are all strong.
If you want to lose weight, cut your carbs and add some hit. (Good Calories, Bad Calories - Gary Taubes... also of course Jordan Feiganbaum) You may curtail your lifting some to get there. So what???
We all can't be Joe Pena. But it sounds like you are certainly stronger and healthier than you were, and you now have options you didn't have.
You can just keep doing 350 until it is real easy. Then move slowly in the direction you want to go, because largely, you're already there.
I find lifting to be a joy. Even yesterday, where my lifts frankly sucked. But I lifted, made progress (from resets), only one lift is potentially within weeks of a PR.
Life is a journey, not a destination.
Listen to better music. (aka less angry music)
I don't lift for numbers. I lift to be better. Decide what better is for you. Decide what kind of better it is "worth it" to be. Go there, who cares how long it takes or what anyone thinks. You are in this, for YOU.
