can't say that i've played w/ one. I have played w/ several production cues, however, from an early stage, i was bitten by the custom cue bug (saw a SW when i was 16 and fell in love).
there are several production cues that are good players, however, for me, and for many here, there is just something about having a custom cue, something that you have designed from the start, from a maker that you've done your research on and waiting.......waiting.......and finally having it in your hands. and this is not to mention that you know that it is a one of a kind.
even if you get one second hand, it's a one of a kind.
there are several makers here that can make one for a reasonable price.
if i were you, depending on how serious you are about pool, i'd stash away a few bucks (i know times are tough nowadays) and invest in a custom cue.
not to knock on viking or other production cues, but i'm a full supporter of the craftsmanship (not to mention the relationship you can build w/ the maker).
