Ah yes... the good ol' "Honeymoon Period."
"I'm pocketing balls, and getting shape, like never before with my new cue!"
"I haven't missed a fairway in a month with my new driver!"
Enjoy it while it lasts...
It seems like the OP is having a Bizarro Honeymoon Period, of sorts.
Personally, I would stick it out with the new equipment... sometimes a tip change is all it takes... other times it could just take an extra week or two. However, I've not had this problem since going to low deflection shafts. After playing with the OB-1 for the past couple years, I can pick up pretty much any cue with a LD, pro-taper shaft and play pretty well with it. Sure, they will all hit a bit different, but the performance is relatively the same, so the adjustment comes much quicker.
Well, actually, I was just getting ready to switch over cases and reviewing all the junk that I carry around, trying to cut that back a little. As I moved stuff around I looked at my new Predator, one of the new Roadline Sneakies, I got to a Schon that I've had for about 17 or 18 years but played with for only a few months, I took out a Scruggs that I bought in 1994, and came across a Dominiak Sweet 16 that I've had for a couple of years and a custom sneaky that I've had for years and a Joss that is only a few years old, an old Viking, and a couple of old McDermotts Additionally there are a few cues that I have sold over the years.
I compared them to my players, the ones that I carry around, two old Predator Sneakies, the old one with the green veneers for the early 90's that I bough new back then (5/16 X 14, pre cat), and the twin with the red veneers from a few years later (uni-loc). They just feel better.
I've played with friends Southwest's, Joss West's, other Scruggs, Sugar Trees, and various others I just like my Predators better, I can't explain why. I know my collection isn't high top end stuff, but they're all quality. Some of you swear by your Joss, or your Carolina, or Jacoby, or whatever, my two Predators just fit. I own every generation of Predator shaft and have tried them all on different cues, perhaps it's all mental. As a species we tend to resist change on most levels, but the Predator Sneakies just suite me.
I suppose that we all have a 'Holy Grail" that is unique to us as individuals, maybe my Grail is just a little more pedestrian then most.
