I've never tried a two piece cue that had the same, direct energy transfer into your hand that a good 1 piece has. No matter how good the joint is, it kills some of the feeling. Even my Mezz, which I thought was pretty fantastic at one time, pales in comparison with a really good 1 piece cue. The problem with most housecues is that they're made to survive idiots banging them around, and thus have thick ferrules, too strong of a taper etc.etc.
When you try a really good, custom built 1 piece snooker cue, you understand what is lost with the joint. Of course the ability to fine tune the balance is lost to an extent, but with quality cues, this can be overcome as well which is proven by the custom ones. Suffice it to say, it's worth the extra cost and the hassle to lug it around. Speed control is just phenomenal. The hit gives a satisfying, clean sound. It has to be experienced to be believed.
In pool, even the best production cues and many customs have not got good balances. Sure, they're solid and have the balance point at good places, but a heavy metal joint here, weight bolt there...It just makes the balance funny. A lot of customers apparantly ask for forward weighted cues, and this presents challenges to cuemakers, which they solve through various means. Very often the cue ends up unevenly balanced, for lack of a better word. My friend had his cue customized with new joint and joint pin, very minutely tuning the balance, and the result was fantastic and better than any cue I've ever seen as far as balance is concerned. The cue just floats in the hand. Even with a great joint and balance and all that, the hit is still dull compared to a 1 piece.
I always wished I could make my own cue, to use my own ideas of how a taper should be, but it's just not cost effective, even with hand tools. But I have some ideas on how to fix the balance and taper of the house cue and to change the ferrule. One day, the dream will come true.
