Hi Anthony. I`m not aware of colour differences between USA and this part of the world, but for a match to your own, you simply send in a sample of your own with your template, approx. the diameter of a pencil. As to densities, as a guide, Toplace density of 55% approx. equals 70% density in `Others`, 50% =65% `others`, and 45% = 60% ------ that should give you an idea of the density to order. I can understand your sentiments about your first bond, but I think you are reading more into it than actually is the case...... it`s easy enough really, as you will see. If / when you go to get it done, let a lot of what you hear there `` in one ear and out the other`` --they like to make it sound complex and almost rocket-science --that`s to make you doubt your own ability to do it yourself ...... have a close look at what they actually do and you will see there`s not a lot to it. Paul.
