Buying Advice 25cc or 35 CC Honda Trimmer (Versattach)???

I love Honda stuff, so Only considering a Honda trimmer.....has to match with my Honda lawnmower,lol So I have dwindled the choice down to either the 25cc or 355cc VersAttach model. Main use will be to trim the grass and Edge it....so will be buying those 2 attachments right away. Not a huge yard...I think the whole lot is around 9000 sq ft..will take 10-15 to trim it.....and then edge it. Down the road may buy the pruner.......I guess my major question is...will the smaller 25cc be enough power to do all that? I just want to buy something that is going to last..and not kick myself down the road that I should have spent the extra $50 and got the 35cc...but I do not want to waste $$$ either. TY
