@Muirium and Beardsmore, forgot to thank you two for the great advice before. At the end of the day I found someone to try the regular with and held out for the 55g variant. Not one single tiny ounce of regret now I've got it, I love the uniform 55g and wouldn't even consider the lower weights ...
I'm currently looking to upgrade from my lowly $20 membrane keyboard for the first time, having done so I've promptly decided to bypass all middle stages and flee right towards Topre keyswitches as my preferable method of torturing my wallet.
