I have yet to play a game where I do any fighting against the HRE, mainly due to their size and I'd rather not start anything that I probably wouldn't win. In my current game as Sicily I'm getting to the point where it's either expand in Spain and France, invade Africa, or fight the Byzantines or HRE. I currently have around 6000-7000 personal levies and 16K vassal and can afford around 6000-8000 mercs per month.
What is the best way to go about taking land from the HRE first? I know that fabricating claims in Italy and then taking dutchy titles is a good way, or getting claims through marriage and sons, but how do I go about fighting an army more than double my size? Is it best to wait until there is a succession war and then grab as many claims as I've been able to get before the war ends?
