S66, since you have the 511, get the 911. The 5 will take care of all the smaller chores and the extra 2 inches on the 9 will only work to your benefit if you are dealing with chopping/splitting wood. THEN you could get one of the elmax blades (the blade show 3.75 incher or one of the ganza 3.4s) for the smaller and kitchen type work.

Oh and I rounded off the butt of the Scrapmax 3.75 just like my Wardog and it is a lot more comfy. <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />
