i have played 10 years straight full time and once in a while for the next 12 years, during that period of time i had 6 cues that were my main weapon of choice and a coupe of back-ups. I have owned 100's of cues(i flipped them for pocket change). What I have learned over the years if a cue is going to "work" for me I know right away, now it might take 2-3 weeks to get there but I know ahead of time,
I bought a Bill Stroud once from Bobby hunter for $1500 before bobby was building cues, i loved it it was the most expensive and first non-production cue I ever had. I had the same problem your having 2 months later I still couldnt make a ball with it....I was sad and sold it. perhaps thats why bobby sold it to me who knows, i ended up real sweet on a trade.
I just started back playing serious a month ago first time in years, and fell into a G.szam, game over i knew in 5 minutes it was perfect for me, I have a fanct Southwest i want to retire its too expensive etc to take to a pool room, the Szam is low key, but it plays better than any cue i have ever owned, Tad's are close as are South Wests, I cant stand TS cues, they look great and i have been beaten with them so they work for some and not for others, sell it now in like new condition and move on, it might just be a bad cue it happens, but you should be able to tell if you can adjust in a day or two to a cue, BTW the Tad and Szam are the only 2 cues I ever owned where i didnt need an adjustment period.
