I'm a little particular in my definition of what constitutes a sneaky-pete. A true sneaky is a cue that looks exactly like a one pc. house/bar cue. So much so that when you get up to go to the can, the bar-maid puts it back in the rack with the rest of the house cues. Then you know you've got a sneaky. I've seen it happen many times.
If you were to have one of these cues and now add joint collars, Hoppe ring, wrap. etc. you no longer have a sneaky, you have what I refer to as a 'fancy-pete'. There's nothing sneaky about it and the only one you'll be fooling is yourself to think otherwise.
Anyway, I digress. The hit of the one pc. house cue is the bench-mark that others cues' hit is compared to. This is because the 1 pc. cue yields the purist form of hit. There is no joint to disrupt the transmission of vibration to your grip hand. There is no wrap that would tend to insulate or soften the vibs. to your hand. Any wrap that is softer than the wood in the cue will act as an insulator.
It's not too practical to carry a 1 pc. cue around in your car. Hence, the birth of the 2 pc. cue. The first key to a firm hitting 2 pc. cue is to make the joint connection as tight as possible. A steel pin into a brass insert does this pretty well, sometimes too well. Have you ever seen a cue 'locked-up'? On the other end of the spectrum is the 'big' pin directly into wood, ie, 3/8x10, 11 or Radial. These tend to yield a softer hit because of the wood threads in the shaft. However, these big pins can give a much firmer hit when coupled with a phenolic insert in the shaft. I've come to believe strongly in the phenolic insert for the big pin. This can enhance the hit of the cue quite dramatically. Since it's on the inside of the cue, no one sees it.
As stated, a harder tip and/or harder ferrule will indeed strengthen the hit but not everyone can play a real hard tip without mis-cueing frequently. You have to have a refined stroke for a hard tip.
Anyway, what was your question again? Oh yeah, who makes such a cue.
Well, just about any competent CM on here if you tell them what you want.
