Best Axe For Tp? Main And Off Hand

Due to congestion in Dynamis recently I've been trying out some oddball axe combos. I've been messing around with mainhanding the OA2-4 axe and off-handing kraken club during WS time. Ruinator surprisingly still does respectable damage with a 37 dmg axe. With red curry I've been averaging about 2000-2400 with the OA2-4 axe on DC mobs. In comparison, my STR magian axe generally does 2600- 3200 when all hits connect. I wonder if mainhanding the OAT axe and offhanding OA2-4 axe would be a viable combo.
