I genuinely don't know the answer but with any drill you need to consider bang for the buck, or to be more exact, time. What is each drill you are doing going to do for your game?
lately I haven't been able to play much, maybe a handful of hours a week- good cos I'm doing other cool stuff, but not the best for pool
typically I'm like you, not a drill guy- but I've focused on a handful of them over the years, ones that I somehow (mostly) enjoyed for one reason or another
the L drill kind of fascinates me because like many other pool things, it strikes me as a puzzle- one with several keys- but I want to find the key(s) that work best
failing to execute is one thing, and can be puzzling itself- but at this point, I'm more interested in mastering, at least in my mind, aim, speed, and spin
so that's the bang for me- not necessarily keeping score, winning, running racks, etc.- I just want to know what's happening on the table.
One that might pay for itself is putting the cue ball on the head spot, any other ball on the foot spot. Now put some paper money at the center diamond of the head rail.
All you have to do is hit the object ball with a stop shot. Drive it to the foot rail and back to the cue ball. The cue ball should roll to the head rail and cross over the money. Calling where the cue ball is going to stop is a good variation.
this sounds fun..will try!
You may find a pattern of common errors in your wagonwheel practice.
the biggest thing preventing me from getting around the wheel was not aiming for a certain part of the pocket- once I started doing that, my % went up a good piece
