I agree that some cues feel much different than others. I also believe that the cue you hit with wasn't good, and that it was assembled from parts rather than being completely made by the cue maker. But, the cause and effect is where I disagree.
There are cues out there made with purchased parts that hit great. There are cues out there where the cuemaker made everything that hit terrible.
The parts that are available out there to buy are made very well. The construction and quality of materials is very high. I think you be surprised by the number of parts these companies make. They are very good at it, because they've been doing it for years, and they make a lot of parts!
Pretty much all cues, that are of traditional construction, are made from parts. When a cuemaker builds a cue, he first buys or builds a forearm, buttsleeve, handle etc. He then assembles them into the final cue. How he does the final assembly is just as important as how the parts are made. If not more so.
At OB Cues, we build everything we use in our cues for a number of reasons. First, our cues are not built from traditional construction methods. We have developed our own technology, so we need to build our own components. Second is expense. Parts are expensive, and we sell most of our cues wholesale and just can't afford the cost of parts.
The moral of the story is this. As a consumer, buy what you like. If it hits bad, just don't buy it. The reasons why can be really complicated. It's not just simply whether or not the cue maker built or bought the parts he used int he cue.
