We just made an adapation for the common DBX bases system to play 15mm, but works also well if you decide to play 28mm with DBX bases.
We played several games, this was slightly different because of a little better cavalry strenght, more efficient models and greater mobility, but overall this is swordpoint experience. We suggest 1500pts for 1000pts and 1800pts for 1250pts.
