I spent the better part of 20 years living in Japan and working in the billiard supplies industry, and Cogs (their popularity and pricing), as well as a few other well known makers in my opinion, are a direct result of the Japanese market influence, and most of all Lucky and his dealings with these select makers. I'm not familiar with the deal he had with Joe of Cog, but I do know of other deals he had with other makers. Most of these deals involved these makers producing cues only for Lucky. In other words, he would tie up a a certain maker into an agreement where anything and everything that came out of the guys shop went to Lucky only. So, for a few select makes of higher end cues, there was a point in time where the only way to get one brand new, was to get one from Lucky, and at whatever price he decided to tag it with.
I remember seeing Cogs at his shop with a price tag of $20K. And, they were selling!
Now as far as playability, Cogs were a very popular cue in the mid 90's, and basically that popularity came as a direct result of the way Lucky marketed his stuff. The Japanese are a very passive consumer, and there is this mentality in Japan where the more expensive an item is, the more superior it is. Obviously that way of thinking has drastically changed as a result of the depression, but in general the Japanese way is still there. I've seen it with musical instruments, rice, produce, high end cues, cars, and even pets!
In the 90's, if you walked into any given pool room, it wasn't unusual to see 5-6 "B" players playing with $5k Ginas. And the reason was most likely because the particular house pro in that room played with a Gina. Move down to the next pool room, and the whole room is filled with SW, because the house pro plays with one.
Back to Cogs. Most every Japanese player I've ever met that owned a Cog have had the shafts turned down in order to make them more playable. I've played with a brand new one with stock shafts, and I found it to resemble the playability of a log. However, when turned down or tapered to a more favorable taper, they can be 'tweaked' to play as well as any other great player out there. The materials used seem to be very high quality, including the shaftwoods, thus allowing for some shaft tweaking. But right out of the box...............in my opinion...............not much of a player.
Opinion only folks.
