Thinking about it today I figured out that I tend to use a lot more pressure with the heavier blades. I don't know if it is subconscious or just trying to compensate for the weight. At first I had a hard time stopping those little blades but now it's just routine. I think for tomorrow's shave I'm going to try the greaves 8/8 wedge on one side and w&b 3/8 on other to see how well I can control pressure with each.
