If its not about the money, ever thought about getting the Flamberge for field battles? Playing as a 2h you often are short on reach, the longer weapons are rather low damage so I usually ended up using Morningstars or Great Mauls. These weapons are awesome but in an even field battle with a lot of long polearms waving around everywhere, you really got to play smart to be effective. The Flamberge however allows you to threaten such a large radius, that having 10 people running around with them will seriously fuck shit up. 49 cut does the trick against any armour and the weapon isn't even unbalanced and fairly easy to use, even up close.
Also, when it comes to plate, you should really switch to the Gothic Plate with Bevor. Milanese Plate + Heavy Gauntlets gives you 79 body armour, but the Sallet with Visor and Coif only gives 63 head armour. Which means that the 79 body armour is a complete waste when a few people figure out they got to hit your head. I always pike at faces and playing as a 1h I always steel pick at people's heads because they die so much quicker. When you take the Gothic Plate with Bevor you get 76 body armour and 76 head armour, which means that your head protection is in much better proportion to your body protection, which I think will increase overall survivability.
Also, you lack hoplite weapons. Ashwood pike is the cream of the crop in that regard.
