Tractor Sizing ym 165 blade size

[gws]

What size 3pt blade would work best on a YM165? 4ft or 5ft?
Main use is snow removal (1-3"). I have chains but not sure of bloade size. I got a snow blower with my tractor but with the small amount of snow and a gravel driveway, I throw more stone than snow.

I use a light 6ft blade on my YM135. I have 70 pounds on my front bumper and tire chains. I also replaced the lift arm links on the 3pt with chain to let the blade "float" better on my driveway contours.
