just helped pro shop guy drill his nano
we bowl on wood lanes with gaurdian and he was bowling in normal shoes so low ball speed
and man this ball still hooks and has crazy backend
didnt roll out even getting it to the dry which really impressed me
i cant even use my prodigy for a couple shots without it leaving 5pins all day
so i wouldnt be afraid to drill it a lil stronger if youre scared about it hitting weak on the less then soup conditions
was like a 4 1/2 x 4 drilling pin = to fingers
