Its not uncommon I guess I'm just weird that actual weight doesn't bother me. Last year I played 125g shafts and dropped to these with no issues.
When I had 120g shafts in the same irons I have these in I had a huge left miss and with these shafts at 105g its all but gone. I wonder if the style of iron and the weight combo is playing any sort of factor at least for me.
There are a ton of potential variables other than weight that is for sure. it could totally be something other than static total weight.
