25.4 Cobb or Hotchkis hollow: Good with heavy sprung coil overs. A little stiffer than your current.
28/29mm adjustable Whiteline. (Not convinced a human can tell the difference between 28 & 29 personally)
32mm Strano.

There may be a solid 25 or 26 out there, but why?

If you are not going with stiff springs to help, your objective is to keep the front end geometry from the dreaded Positive camber land when the arm goes above parallel and the body rolls and your outdise front ends up with +2 degrees of camber or so, so bigger is better.

The biggest downside will be in the rutted winter roads where you may the ability for the fronts to follow the contours. Though it is only about a 1 - 2 hour swap depending on skill and tools. A shop with a rack could probably do it in 30 minutes.

If you are going big, I'd do the Strano.
