Ok... shortie here

biker chick - 5ft3 inches tall
ride a 06 Dyna with a high flow air intake

The biggest difference I have found it the seat. I sent mine off to Mean City Cycles and had it lowered, sides shaved off and back brought up. The ride I went on after it came back was a world of DIFFERENCE! *haven't been able to do much riding since it came back as I hurt my shoulder at work and waiting for it to heal*

I used to rest the back of my ankles on the mid controls. With those changes in my seat I rest mid calf on my mid controls. Now looking at highway pegs!! Yeaaaaa!
