thanks -
i don't think i'll be pushed up into the windblast to the same extent as i'm a different build to you (i'm 5'8" and slim) and also, i don't tend to get up to very high speeds 'cos for career reasons i have to avoid brushes with the law therefore 100mph is generally fine for me.
what is in issue isn't just the weight on my wrists, as the existing risers have reduced that, it's the steep angle of the bars making full lock turning almost impossible - not to mention that i still have to crane my neck to look at traffic lights and as i do most of my riding in london, that happens a lot
