I like the deflection and armor ones. The deflection feels like the Deflect Arrow, plus some others like the epic version, but works fine for a fighter blocking visible stuff with his equipment.
The armor one may look a bit overpowered, but I think it may just give him the edge he need to not be completely shutdown in less than 1 round. And since it's still possible to fail, it's fine.

The rope one is like a ranged lock-down combo. Don't know if it's good or not.

The item creator one looks more like something to fit a PrC than a feat chain.
