Back/Biceps

So I did a Back/Biceps workout and added a bit more volume. No PRs were broken and it was an okay workout. My form/reps got a little sloppy at the end. I'm really trying to figure out how many sets are good enough for me. So I tried a bunch of exercises this workout. I think in the future I'll just stick to 3-4 exercises and do more sets of them.

BB Rows- 275x7,x5.x4 (almost 30-60 second rest in between)
Pull ups- 50x7,x6 (underhand), 25 (overhand)x6
DB curls-35x9 each, 40x8 each, x8 each
BB Curls with a little cheat- 120x7, 125x3 drop set 65x16
Pulldowns- 160x10, 180x8, 180x8 cg, x7 cg
DB rows- 85x15, 100x10
Cable Row- 140x20
Hammer Curls- 50x10 each, x9 each, x7 each
CG EZ bar curls- 60x10 (kind of pointless set lol)

So from this workout I think my biceps can take 9  sets with my Back muscles. By my 10th set it just was not worth it. I think next week I'll shoot for 9 or so. For my Back muscles I did 13 sets and that seems to be about right. I'm going to switch things up for next week and do something like the following:

1st exercise- Weighted pull ups. Warm up and then do a RP set 3 times
2nd exercise- BB Rows- straight set- shoot for 8-10 reps
3d exercise- Hammer Curls- 3 sets as heavy as possible 6-10 reps
4th exercise- DB rows- 4 sets 8-12 reps
5th exercise- BB curls, 8-10 reps, maybe start at 100lbs?
6th exercise- 1-2 set of high reps for back, whatever exercise I feel like.
7th exercise- Biceps exercise, probably DB curls- 6-10 reps
