Another bonus of deleting the balance shafts is that it increases your oil capacity but up to 1L which makes it much more unlikely that you'll encounter oil delivery issues in super tight right-hand corners. Normally in really tight right-handers and round-abouts you'll have oil shift away from the pickup tube in the pan and then you get that oil pressure light and bad things can potentially happen if you're pushing the engine at that moment. But with an extra 1L of oil that won't happen nearly as easily.
I generally wouldn't recommend the oil pump delete to anyone without a significantly modified car that runs high RPMs and/or track use, and I also would never recommend the unfortunately popular 1.8T oil pump swap as it is not as seamless nor as safe as many would have you believe (it does not deliver ideal oil pressure either).
You're generally unlikely to encounter oil pump failure unless you are A) modified enough to reach those limits, or B) have poor maintenance practices (bad oil, bad oil change intervals, non-OEM oil fitler, etc.)
The new LM MolyGen or whatever it is called is not as good as the oil that was discussed thoroughly in this thread. I strongly recommend you stick to the LM Leichtlauf (part number 2332).
If you engine sounds "angrier", and if that's not in your head, then that is a bad thing.
