... and by using a longer focal length lens, you are using the center of the glass which is reputed to be the best part.

I would stick to either a 135 or 150 on a bench enlarger. I sometimes use a 180mm for small prints, but I wouldn't buy that as my primary lens for 4x5. Properly aligned a quality lens will be sharp corner to corner. If the corners are fuzzy it's almost certainly an alignment issue.
Various folks have complemented my sharp prints (I wish they'd say nice things about composition or subject matter as well ) over the years, and I've used a 135mm Rodagon 90% of the time (and a 150mm Rodagon the rest). I can't say I've ever noticed distortion or vignetting ever, even printing edge to edge of a negative. I print everything at f/11 for sharpness and controllable exposure times, and rarely print larger than 16x12".
Marc!
I've been happy with my 135mm lens... wouldn't mind having a 150mm though
