Hi folks, it's my first time here - so be gentle with me!

I've recently returned with gusto to 35mm photography having bagged myself a fabulous Contax G1.

Having studied B&W photography as part of my design course at college (about 15 years ago) I had no problems developing my own black and white negs.

However I just can't get to grips with C41 colour. My results are consistent but consistently poor.

The negs seem a little dense and lacking in colour - especially blues.
The results through my neg scanner (don't have room for a darkroom at the mo') are very pale.

As I said the results are consistent - this is my 3rd roll developed (but I've used two different filmstocks so far).
Each time I have strived for more temperature and timing accuracy than the last but with little improvement.

I'm currently using:
Fotospeed C41 Press Kit Dev and Blix
In a standard Paterson tub
And have used two different thermometers (went digital for more accuracy) and monitored the temp at all stages
Timed on my swiss railway watch.

Am I doing something fundamentally wrong?

All help and advice gratefully received!
