Discovering new preferences, and reminders of the fundamentals
Maybe your grip hand prefers a wrapless cue and you never realized it!!!
Maniac
I think Maniac hit on something here. (Good job, M!) I personally discovered my preference for wrapless cues by noticing this "feel more confident shooting with a house cue than my Irish Linen-wrapped two-piece" long ago.
The other thing I noticed is that with a foreign cue in my hands, I tend to pay attention more to my fundamentals *because* of the foreign feeling in my hands, than I do with a cue that feels familiar in my hands. It was an indirect thing -- I thought to myself, "why is it that I seem to not miss" when using a foreign cue, than when I'm COMFORTABLE shooting with my trusty old familiar cue? After some soul-searching and some analysis at the table, I found that I was "unconsciously" paying more attention to my fundamentals (if that makes sense to "unconsciously" "pay attention") with the foreign cue, precisely *because* it felt foreign. I'd gotten lazy because of the comfortable feeling with a familiar cue.
Then, I took my trusty cue that I'm comfortable with, and made a conscious effort to pay attention to my fundamentals -- stance, hips, knee joints, where the feet were placed, bridge hand, grip, alignment to the shot, etc. And voila! EUREKA! That "seemingly couldn't miss" feeling was back.
Sometimes it takes an outside influence (e.g. a foreign cue) to remind you of the basics / fundamentals.
And yes, let's not forget the importance of what Maniac hit on above as well -- sometimes you discover a preference for something by trying something new. Today, I still prefer wrapless cues, and I enjoy the art / craftsmanship that a cuemaker shows off in a wrapless cue, because he/she can no longer "hide an ugly / so-so-looking piece of wood" under a wrap.
Hope this is helpful,
