no carry on giving comments mate, its left to the user if he or she takes it onboard :)
yes i know the weight thing and i always try to model as it would be in the real world as that is what my clients pay me to do:). although sometimes its nice to do something that is just foolish in a technical manner but nice to look at. god knows ive done a few of those. i shall attempt to make a start on the mech 1 concept as i feel it is better, but though i would practise on his poor little weaker brother first :)
so keep replying and keep watching mate
