Ok... for now I'm building a Dwarf Battlerager Fighter/Dreadnought with a mean execution axe. 
I'm going for 20 Str, 22 Con, 16 Wis. Basically a fighter with REALLY sucky defenses but a LOT of hp and temp hp. My calculation for now is 146 hp with 17 healing surges for 57 hp each. And then, 6 temp hp when he hits with an invigorating power, and 9 when he is hit (thanks to Dwarf stoneblood). So, should be pretty durable with the help of a leader.
Now, what I'm having some trouble with is choosing items. So I would gladly hear some advice.
For now, I chose a brooch of vitality +3 as 15th lvl(for the 5 extra hp),  a Bradmail of durability +3 (for the +3 to surge value and chainmail for battlerager +2 to dmg) and a Berserker Execution Axe, which is a 15th lvl too.
Now, here is my doubt. The attack bonus won't be nothing to write home about (+17 with this equipment), though i'm counting on flanking pretty often if not almost always thanks to the pass forward at-will utility; so, would I be better with a simple +4 Axe? The berserker would give me +3d10 on criticals in addition to the nice daily, while the magic axe +4 would give me +4d6, and +1 to-hit. I considered vicious and bloodiron too, but they're either lower or higher lvl than needed. The executioner axe is a high crit weapon, if you were wondering.
Or maybe I should just get a mordenkrad and Hammer rhytm?
Suggestions?
Or, alternatively, Redclaw, can I use the difference in money if I choose a lower-level item from the free ones?
