I dont know the 10 board from my thumb hole size, but i am still trying,God only knows why.I have been bowling a couple of weeks now with an epic battle and as best as i can figure there is never gonna be enough oil for this ball in my hands. I say this because my team mate through it and it was amazing off his hand. In my hand it was a sphere that rolled down a surface eventually ending up in the pit.
    My query then is this ,and i have had some positive input on this topic , but anyway,what should i be throwing. I have thrown the big one wmb and now the epic battle and non of them have i been able to use. I just picked up an overtime and its a good ball ,but i am finding that where the battle is too much ball the overtime is still really not enough. My battle is drilled stacked 4x4 . pin is at 4 oclock and almost touching the ring finger. overtime is drilled 4.5x3and 3/8. it rolls really nice ,but where the epic nose dives it leaves the 10 pin,and i have nothing to fit that void.I am presently using (because my other stuff was stollen),ninja fury,hercules,turbo xl,(1in.pin),and a polished power groove. These are all decent for med to light short patterns, but its the intermediate shots where ,the battle in my hand ,is too strong , that i need help with.

I think its more of a coverstock issue.  All the coverstocks you have chosen have been tremendously strong.  And without good direction and ball speed, this will make all these balls roll out or barely arc.  They are made to arc in heavy oil being thrown by the best.   They are not for the medium or low oil house shot by those with low rotation and/or ball speed.  

I would suggest that you move into a intermediate reactive that is a solid polish finish.  Storm has the Thunder Road, Hammer has the Vibe, Ebonite has the Ice (maybe even the Big Time Pearl) for a few suggestions.
