I've got 19 rage rounds a day, which I hope will be enough in most cases. So I guess the answer is yes to raging most of the time - which is also my 'shtick' for the DR thing ;)
The added cost for adamantine is a flat amount per weapon, or does it depend on weight, or being heavy/light weapons? (I could look it up, but I am kicking it at the beach so...). Just wondering if it is best to add it to a secondary weapon until I am in front of Herolab, to have it answer my question :D
