Personally, I'd always try and go for the situation that would work best in an emergency. If I was dazed and needed to get out of the car fast, would I want to be faffing about with the wheel?
Originally I went down to a 13" wheel as it made entry/exit and driving much easier, although I thought it looked a little 'micky mouse', This year I've made a concerted effort to shed some timber and have dropped from over 18st to under 16st and have gone back to a 14".
Good timber felling.. Well done.
