Hey Big Ed - A few years ago I went with Cruiser Performance Punisher 8x8 Handlebars (8" rise & 8" pullback). I was told this is the furthest I could go without changing OEM cables and I believe this is correct. I'm 6' 1" with pretty long arms and feel these are just right for me. I'm wondering if your wife might find more comfortable with a 13" pullback? Granted, this will require new cables but you might avoid buying 2 sets of bars.
