Dan,
   I have a Hartzell Scimitar = 3 blade on=20 my ES.  My plane also has a Lycoming IO-540 in it, which I = believe is=20 a bit heavier than the IO-550 (I'm not so sure it's heavier than a = TSIO550=20 though).  I had a custom made mount fabricated for the 540 which is = much=20 beefier than the stock mount that comes with the kit and is, = therefore,=20 somewhat heavier.  I also mounted my battery on the firewall as = well as=20 a preoiler, which probably weighs about 6 pounds.  Finally, I = put a=20 polished spinner on the nose, which is certainly  a bit heavier = than the=20 composite one.  About the only things I did to counter all of this = is put=20 an oxygen bottle and a halon fire bottle as far aft in the baggage area = (which=20 goes 16" further aft than standard) as I could.  I also made my = elevator=20 trim tab a bit wider than called for in the book. 
   Even with all of this, my = CG is right=20 at the forward limit with me in the plane by myself.  As I add = fuel,=20 passengers and especially baggage, it moves back.  The A&P that = helped=20 me with my weight and balance was amazed to learn that there was no=20 configuration he could come up with that put my plane out of=20 CG.

   The bottom line here is = that I fully=20 agree with Kirk: get the best prop for your plane and don't worry about = the CG -=20 it's not THAT big a deal (at least it wasn't for me).
