I highly recommend the Timeless Crown handle in titanium. You can get it through their scratch and dent section. Initially I thought it was rather ugly, but when I got it in my hand and shaved with it -- wow. It is nearly perfectly designed and works really well with a Game Changer head and most others. Get one, you'll likely end up wanting to use it with most of your razors.
I have the Razorock stainless steel UFO handle which is 85mm long and weighs just 65g. Wish it was a little lighter but length is good and weight is ok.
