Got fitted for a mallet and my lag putting got worse

[EagleEye_Ed]

Went in for a putter fitting back in March. Guy puts me on Quintic, tells me my old Anser style blade is fighting my stroke, my face is open at impact, all that. Walked out with a Spider X, slant neck, 34 inches, way heavier head than anything I've ever rolled. For reference I'm a 9 and lag putting is usually the only thing keeping me under 85.

First two weeks on the practice green it felt unreal. Ball came off dead online, short putts were automatic.

Then I actually played golf.

Anything over 30 feet I'm either leaving it 5 short or blowing it 4 past. With my old blade I could feel the head the whole way and my speed was honestly fine. Now it's like swinging a hammer with no feedback at all. My 3 putts went from maybe 1.5 a round to 4. Shot 87 last weekend and I swear 5 of those strokes were just lag putting.

The annoying part is 4-8 feet has never been better. So now I'm stuck. Keep the mallet and live with the lags, or go back to the blade and give up the thing that's actually working?

I know it's probably me and not the putter but I'm 3 months in and it hasn't clicked. Anyone made the switch back to a blade and regretted it? Or did you find a mallet that actually gives you some feel?

New here but this is basically my exact fear. I got fitted into a Spider X too (used one off a buddy, slant neck as well) and my lag putting is a disaster. Everything inside 6 feet is money though so I get the dilemma.

Random question, did you ever try choking down on it for the long ones? My pro told me that helps with the heavy head but honestly I can't tell if he was just making conversation. Also does yours have the stock grip? Wondering if a thinner grip would bring back any of that feel you're missing.

3 months does feel long to still be fighting it. Kinda leaning toward just going back to what worked for you on the lags and eating the loss on the short ones. Easier to practice speed than to fake confidence over a 4 footer.
