Just in Cameron putters, even LH there are plenty to choose from.
Mallets now come in multiple toe hangs. Best to find a putting studio to find your swing characteristics and then match you This can get pricey but you can use a putter for many years when it works well. Trying a couple of putters at a golf store may not set you up for success round after round. You likely got hot for a few strokes, not it was the best setup matched to you.

Scotty Phantom 5 or 11 depending on your stroke. There are some different offerings with different neck styles but anything from the Phantom line is a solid option if a mallet is what you are looking for. Each model offers something unique on its own, head shape, alignment features, etc. See what feels best and suits your eye, Scotty is heavily favored here as you can imagine and if that’s what you’re looking for the Phantom line for mallets is my recommendation. I personally own the 11 and 11 Long Design, both are great for different reasons.
