You were right about the stock 200 case failing eventually, not if but when. I just finished reading the "Red Book" again and in the back is that very issue addressed. Something about putting the heavier duty CLE internals into a stock 200 case to make it more HD. Regardless, I am happy I am buying the rebuild 225 Promax with sporty lower. Thanks for your advice and guidance. Now to sell my 200EFI. Craig
