picking between the acrylics and the roughstacks was a tough one, roughstack is more durable but the acrylics were prettier, i love the bluelightning pattern but bumping down to a 14500 when my diy tuber is 18650 was a no no, the goldrush is an 18650 but i can't stand the pattern. didn't know about the golddigger, nice find, but with the 4.8 nimh battery it kind of nulls the ten dollar difference between that and the goldrush.
