First, don't rely too much on the shavette feel. It can lead you to think your real SR isn't sharp enough (as many before you have posted).

But also, don't be afraid the little blade. 4/8 was the last new size I tried and it's a hoot. Probably not the easiest one to _learn_ to strop with, but once you get a stropping stroke down, they "turn" really quickly.

What matters most (after proper prep) is sharpness, angle, and pressure. Actual blade width, is only slightly above scales material in importance to the shave. IOW it's just a preference thing. Heavier blades have a "flywheel effect" if you know much about mechanical things. It might seem silly at the mass and speed we're using but Newton's Laws do apply.

So far I've used 4/8, 5/8, 9/16, 6/8, 7/8, 15/16, 8/8...various hollows to wedges (honing a 5/8 DD wedge now). They all shave as good as their sharpness.

One-handed shavers may find some sight lines blocked by bigger blades. Then you learn how to look "around" the blade...

Let us know how it works out.
