Ask an Aran thread.

seeing those are expensive equip. I assume your other atk gear is at least "good", then the superboards wins in dps (in training hko rate is important but on average the superboard still wins in most cases). By good gear i mean anything like a glove over 10 atk and 2atk cape etc allready..

With the super board you need a little over 90% (90,47619) of your Total atk with the blood board to even out, and by Total atk i mean including glove, blessing, potion, ring and whatnot
The only thing i didnt include here is the Str difference on the weapons, but then again the walking speed on the superboard is a factor in training too :p

As for the question above idk

I'm a little confused at your statement. About the supersnowboard 90% of my blood board thing.
