Most who changed to bulky steel like Step and LS5, etc, hate it at first. (also other steel as well if the old steel ends are banana shaped) But, the answer is simple, if these areas are bothering you while skating and you have given your muscle memory time to adjust to the new skates, holder and new steel, then by all means have some of the metal in those areas removed. Don't hack it all off at once, do it in small steps until you feel comfortable. Removing too much may "feel" better because that was what you were use to, but it doesn't always mean it's the best for performance.
