365 is monstrous, good job man!
Do you still do your super arch? what pointers do you use for your bench form? What are 30's?
Thanks. 
i have a bit of an arch (my back is oddly flexible), but nothing remotely like i used to. i keep my feet flat and i'm not near the point where my abs feel stretched or my spine pinched. just enough for my shoulder blades to stay tight and my hips down.
the biggest tips i have would be the following:
1) find out what grip works FOR YOU. i'm 6'2" and my arms are on the shorter side, but middle finger on the rings seems golden for me. i know guys that bench by putting their thumbs on the edge of the smooth and then stretch from there, probably four inches INSIDE the rings, with arms as long as mine. i also know a guy who goes index fingers on the rings and is pretty small, which gives him a real short ROM but still perfectly competition legal.
2) plant your feet in a way that you can push, but your ass doesn't pop up. for some it means mega wide (i believe wolfe does that), ben white has his feet way close but toes ducked out far. for me it's somewhere in between. i've tried the other two and it just didn't work as well.
3) KEEP YOUR HEAD DOWN. don't lift it off the bench.
4) don't just think of "lowering the bar to your chest", also think of "lifting your chest to the bar". it'll help you keep your back tight since it removes the tendency to let everything fall apart on the way down and then try and "regroup" for the push up.
when i say "30's" i refer to an exercise a friend of mine showed me. you take the bar with a real light weight (he strips 3 plates off his max, which means 225 for him

) and do 10 really small reps at the chest, then 10 small reps at lockout, and then 10 full reps. i almost puked after the first set of those today, probably because i'd just knocked out all those reps with 225.
anything else, feel free to ask.
