Snag a lesson from a local pro, may be a very simple fix that you aren't noticing and they will see. I recently had a moment like this, cleaned up a few mechanics w/ one lesson and dropped my scores significantly.

Shy of finding time with a pro, i find that going to an open field with a bucket of balls and swinging 50% with a concentrated focus on swing mechanics helps me get on a consistent path and face contact.

Agree with both. Get to your pro if you can as like Christopher said, they may notice something simple you're missing. Otherwise hit the range and slow it down, way down and concentrate on the mechanics and feeling the clubhead. As you build it back up, remember no matter what you saw occasionally with Tiger, most pros are swinging on average about 80% tops. Don't overswing. Easier said than done as I've been swinging too hard for years, and finally got it slowed to smooth and letting the club do the work with great results.

I have had many different clubs from other manufacturers and Titleist are the best I ever played witf

Feel your pain. Not hitting the ball consistently right now. Nothing seems to be clicking. Not seeking advice but am playing with my teaching pro on Wednesday. Know it is an easy fix and he can take care of it. Pretty sure it has something to do with tempo as it does most of the time. Can always count on my PGA pro.
