I rode the 390 Bosses for 2 seasons and I highly recommend those bindings. Two of my friends have purchased 390 bosses under my recommendation. The level of adjustability is insane, and they have enough flex to be fun, while still being stiff enough to handle jumps and steep. The canted foot beds are awesome too, taking pressure off the inside of your knees to keep you comfortable for the whole day. Rome also has an excellent customer service program, and the auto-strap feature is really neat too.
I currently ride the Union Datas and Union Atlases, and enjoy them because of their high quality of build and simplicity. I would recommend the Contacts or Chargers over the Forces, however.
I would not recommend Salomon or K2 bindings, as I feel that they are sub par on a variety of levels to the Rome and Union brands.
