I wanted to put the Start up against the smoothest razor in my den, the RS10 Ti.
Preshave- Hot shower & Castle & Forbes pre-shave
Soap - Castle & Forbes lavender
Brush- Carnavis & Richardson B3
Thayer lavender and Castle & Forbes lavender balm to end the shave.
I used a 2 use Persona Red in the Start .90 Sb vs RS10 Ti aggr plate
First pass WTG. The RS10 is significantly lighter and was a little smoother WTG, minimal blade feel with either razor but they both took down the majority of my 24 hour growth.
Second pass XTG. Again the RS10 was just a touch smoother. Cold water rinse and the RS10 side was only in need of a touchup under the jawline and the upper lip, the Start side needed more on my neck plus upper lip and jawline.
Third pass ATG. I was really enjoying the shave so I did a full lather and did a complete ATG pass. Both razors handled it very smoothly with a slight nod to the RS10.
I got a wife tested BBS shave with both razors, no irritation at all. I would say the RS10 is still the smoothest razor in my collection, the Start( especially based on cost) did very well but was slightly less efficient and not as smooth as the RS10.
