Ok, CueTec's are a nice cue to start with. My cousin has a CueTec Break/Jump cue which I feel is one of the best out there and he plays with it as well...don't know why, but he does. Since then, he's gotten some sort of sneaky-pete. (haven't seen it yet...) Well, I tried playing with his b/j cue, and in addition to the cue being too heavy (20 oz.), I really...really, really, really hate...no...I mean LOATH their fiberglass shaft!
Also, I don't care how long, how loyal, and or stubborn you are about your production cues, CUSTOM CUES PLAY WAAAAYYY BETTER...PERIOD!!! Let me put it to you like this. Even though I have ordered two Cokers (which are custom cues for those who don't know...), I long for the day I can hit a Lambros again. I still remember how that thing felt when I hit it in Valley Forge in 2000! Yeah, I could've had one by now, but I wasn't that serious about the game as I am now, and I couldn't see plunking down $900 on a plain jane, because I was going through my "pretty cue" phase.
The cue I hit at VF was $1600 and I didn't have that kind of money then or now for that matter. Now, I have nothing against production cues, nothing at all. My favorite cue, even over Schon, is Joss. Yes, the pros play with Meucci, Falcon, Joss, etc. but they can afford to support the pros; however, there are a lot of pros who play with custom cues as well. Efren, Mika, Gabe, Sombojin and many more.
I bet if you were to do a blind hit test between various production cuemakers and custom cuemakers, (stay blindfolded and let someone hand you the cues and line you up...) had that person write down your responses, you might be suprised after you finish, what you really like.

I still love Joss, because their cues taught me that a cue shoud feel solid. Now, I need a cue that will give me a solid feel/feedback and I think that a custom cue will do this better than a production cue.
Let me also add, this depends where you are in you game too. You may feel that a production cue hits just as good as a custom cue and a lot of people do. But here's something I thought about. O.H.B. has said on many occasions that he has an original Balabushka put away for safe keeping and he uses a Lucasi (which are excellent cues from what I've been told...), to play with now. He had to make some necessary adjustments, but he feels his Lucasi plays extremely well for him. But, he's in this game for a good minute so he knows what the hell he's doing too!
My thing is this, not all custom cuemakers out there charge $900 up for their cues and for the price of a lot of these production cues, you can get a nice custom cue made. I look foward to my fancy Coker sneaky-pete next month and my custom in August. So yeah production cues are nice but I assure you, you can find a custom cue maker that'll make something that's best for your game for a good price. Ok...I'm getting off of my soapbox now.
