I agree. THe quality of the shimano cranks and chainrings is very much above that of the FSA crap... errrr... crank, so swapping might give you lower gears but also might result in poor shifting, faster component wear, and snaped arm and/or legs. You can get a 39 or 38 tooth small chainring for the shimano crank. 53-39 is a very common combination on double cranks and there is generally no problem with shifting.
