I just ordered a guts Tall soft foam seat and decided I must also purchase some new handlebars because i want something higher. I want to stick with 7/8ths bars. I'm leaning towards the Button Renthals and the Protaper KX High bend. I've checked the specs on each, the Buttons are a tad higher and have more sweep, not sure if that's good or bad. I think I will also gets the tusks risers too. I had lot's of back problems last year and I'm hoping that being less hunched over while standing will help. Which bars do you think I should get?
