Thanks ... I'm getting some good options to check out. I wish I had better results with my fusion surgery like some have had here. I use a mirror since turning my head is pretty limited, and I have chronic (low grade) pain issues with any rides over 40 or 50 miles - hard to hold my head up. And I've tried all the standard remedies like a tens unit, physical therapy, acupuncture, massage units, heat/cold gels and pads, gym, etc.
Like you, I've found that my handlebars have to be level (or actually higher) than the seat to work for me; I'm using a Jones Bar which has worked out well for giving me different hand positions (including a 'cruiser' style upright position). But I'm beginning the long process of researching custom and stock frame options that might be viable.
