85L for thru hike?

"I know its a bit overkill, but i like the bag a lot." 

In all honesty, that is all that matters.  None of us will be carrying it;  if you feel you got a good deal and it suits your needs, I wish you all the best with it.  I have a beat up old, ratty looking pack that most would laugh at but it has been though 5 countries with me.  It is an old friend with a lot of memories associated with it and while others might look at it like road kill, I will never part with it.

As the saying goes, hike your own hike.  I would add to that: make your own memories.
