Hi Marius,
thank you very much for your information. After sleeping over it i thought takeing it to an expert would be a better option. First of all it was quite expensive and it would be a real shame if i try to "optimise" it and ruin it forever by doing so and fail miserably at it.
Its very hard not to give in the urge to present it already now, so will present it to the forums for discussion when everything is finished.
Thanks again
