I am going to replace my 9 speed shimano ultegra groupset (one day) and I am not attached to any particular brand, they all have their merits. I am looking for the one which suits larger (I wear size XL mitts) hands for when riding on the hoods. (I'm a function before form sort of person).

what do you suggest and why?
