I was looking at the checkmate lawn striping unit for my 48" Scag Walk-behind. They recommend that you get a roller that closely matches the outside width of the drive tires. By doing that you wouldn't be getting the full striping effect with each pass. I think that would then make the stripes look funny. Of the 48" stripe, about 40" would be with the checkmate and about 4" or so on either side of the stripe would not be as defined. They say that if you go wider that it makes it more difficult when you are going around tight areas like walls or foundations. When you go to their demo on their website the guy running the walk behind has a very wide roller (as wide as his entire stripe). Therefore, would it be a waste to get a roller that is only as wide as the drive tires? I think my mower already stripes well, but I wouldn't mind making my stripes more defined.
