Reddit reviews Slovenia/Croatia/Bosnia Marco Polo Road Atlas: 1:300 000

I'm doing a similar route this summer too.
-Vienna to Athens, via the Adriatic coast.

I'm doing some broad planning with the computer from home, and discovered a few things:
-Streetview is great for deciding what sort of roads you want to ride on.
-https://maps.here.com/?map=46.16337,24.26012,6,normal is better in some ways than google maps because it allows more waypoints.

• I rode across France with a bound version like this: http://www.amazon.com/Slovenia-Croatia-Bosnia-Atlas-Marco/dp/3829737084/ref=pd_sim_14_6?ie=UTF8&dpID=61FD4X4L%2BML&dpSrc=sims&preST=_AC_UL160_SR130%2C160_&refRID=1456Q75YKHRG4EGHXQ4A
  it was much cheaper than buying the individual maps. - this was pre smartphone though.
  -This site is pretty handy: http://www.opencyclemap.org/
  I'll pretty much just wing it once I get there. No fixed plans.
  It's good to have a paper map for conversation - not just to help with directions, but telling people where you've been over a beer too.
