Overcoming the symmetry tool in C4D

A few days ago I followed a tutorial that showed me how to create a humanoid head in C4D which didn't go too well at the time. This was partly down to how some of the tutorial was written and also because of the difficulty of using the symmetry tool. The symmetry tool can be of great help when modelling a character as it quite literally does half the job for you but there is a lot that can go wrong when using this tool. One of my previous efforts started to show signs of a bump which ran down the middle of the model. No matter what I did I couldn't rectify this problem however not all was lost as I managed to disguise the defects. I then found the tutorial mentioned above in the hope that I could learn how to avoid the common mistakes often associated when using the symmetry tool. I found the tutorial frustrating at first but on the whole it did teach me some valuable information that I would have not known otherwise.

For my first try at using the symmetry tool I used a primitive cube object which I placed in a HyperNurbs object. I then placed the cube object under symmetry and then placed both of them under HyperNurbs. Now it was this mistake that made the modelling process difficult. Instead I should have cut the primitive object in half and then placed it in a symmetry object. This made so much sense and I don't know why I didn't think of this in the first place. There is still the risk of a split down the middle of the model if a selected polygon is pulled outwards.

I have just begun a new model and I am pleased to say that this one is going smoothly thanks to the symmetry tool.

Below is my effort from the tutorial. The model on the left demonstrates what happens when I connected all of the objects together. For some reason the pixels seem blocky compared with the model on the left.
