@SterFry AFAICT, the head geometry is identical between the older DX and newer SR version, but DX is a more luxurious, premium product, especially the one with real wooden scales. In terms of usage, there is (IMHO) no difference.Have you tried the DX? I'm torn between it and a SR. I already have an SS. I love it, but want to try something where imward pressure isn't necessary
Personally, as someone who owns Japanese style SS, my preferred choice would be the DX/SR western style, but with resin handle, instead of glossy plastic... can't have it all I guess
TL;DR: get the SR, save significant amount of money.
