Just my opinion, and I'm not a good putter so take it for what it's worth.
It can come down to whether you try to set the aimer and then hit the ding, or just leave the aimer relatively close to the hole and adjust your "aim" by intentionally missing the ding. If you are the latter, you might benefit from a putter with higher balance/precision and lower forgiveness.
If it were me, and again only my opinion, I'd wait. You are still at the point where Levels will fly by relatively quickly until you the upper 80s. The L70 Titleist is regarded by many as the 3rd best putter in the game behind the L98 Titleist and L101 TM. That's what I'd go for if I were you. That will last you possibly forever, but at least until you reach the 98/101.
I've got both the L98 and L101 currently, and they do help with certain aspects, but until you learn to correctly read the subtle breaks and match speed to path no putter is going to be a magic wand. Now they can help if you are aiming for ding and miss ever so slightly, or help with consistent distance control, but it still comes down to green reading.
