Just regular paper targets and a spotting scope will work just as well. Not to mention you can tell how you are doing from session to session and measure progress.
That way every round has a purpose instead of turning $$$$ to noise.
that is a good point about paper and seeing your impacts
I abandoned paper for steel simply because it is often raining here and paper gets soggy
I use oversized gongs to reduce the swinging and also to be able to examine impacts as a lot can be learned from impact pattern
As for sticks - they are commonly used here. More often than not people use quad sticks which offer a greater level of stability over twin sticks for very little increase in weight and complexity
With practice and correct stance almost bench rest stability can be enjoyed.
Strong wind is a limiting factor though as the shooter does get buffeted around a bit
