I've drilled everything from Roto for the past 3 years and this is one of my hard ones to find a condition for. I bought the Quest because it replaced my Battle which did not match up for me at all plus I love the Original Epic and the Quest has the same weightblock. I drilled mine pin under at 4 3/4" and the MB at 45 degrees. This does make it roll heavy off the foul line and you will not get the backend reaction of a Mystic or the Cell. But, being 2% particle, it will handle more flat oil and longer oil patterns then the Cell, in my opinion. I have 2 Cells, one 4 x 4 and the other 5 x 3 and on heavy patterns, even slowing the ball speed down on my first Cell at 1000 grit, the Quest will read the pattern better and have a more readable look. I'd say the Quest is condition specific, like all dull particle balls are, but if you get that right condition, it hits and carries nicely. Got that good old Epic roll to it.
Good luck,
