Best 450 Battery / Prop Combinations

[Witterings]

Hi, I'm using a DJI 450 with Zenmuse Gimbal / GoPro, I tried 2 different batteries but am about to get some more.

I've a 3s 5800 which I'm using with DJI 10 x 3.8's and I have a 4s 4500 that I've used Graupner 9 x 5's and am getting about 9 minutes safely with both but would like to try and get another couple of minutes if possible.

I've seen conflicting reports on whether you should run 10" props with the standard DJI motors on 4s, I'd be really interested to see what others thoughts are on that, it's not worth an extra minutes flight time to lose a motor mid air if people think that's where it'll end up.
I'm also contemplating trying some 4s 5800's but I wonder if that's just going to push it through the cusp on weight and won't get any more flight time but just put more strain on the motors.

On the 3s set up do you think it'd make and real difference changing 10 x 3.8's to 10 x 5's or nothing that you'd really notice ???

My flying is for photo / video so I don't need incredible punch outs or anything but would rather the smoothest combination I can find.

Any input appreciated!!
