So I have to confess, I am struck with a bit of envy when I see plus size monsters. However, I have a few 8/8 in my to-do box and for some reasons, they never made it to the top and are still seating in their box, waiting for attention.
I am perfectly happy with 5/8 and I like shaving with my 4/8 as well (especially, when it comes to getting under the nose).
Same with me. I like the 5/8 and probably use one 90% of the time. When I was starting out I thought the larger razors were easier to use but as I gained experienced I liked the smaller, nimble sizes.
