I recon my gantry weighs at least 100kg, surely reducing that alittle with a lighter profile aluminium wouldn't hurt??

Ok I guess your main profile is 160x40 and top/bottom profile 80x40.? The weight difference between HD and light for 160x40 is 3Kg per meter and 2.5kg perM on 80x40.
So lets say gantry is 1500mm wide so in total your only saving approx 12kg and this won't make a huge difference in performance. The extra strength it provides will be more beneficial when cuttng hard than the any slight speed it may gain.
