Alright, this article suggests that Mars could use any of the four described methods, but I’d likely use either the Munson system or the Kniffin four-armed Umbrella out of the listed options.
This article is also nice for helping sort through what factors may lean towards or away from one method or another, so that’s useful if not as crystal clear as I wish (e.g. listing out and describing the ensuing methods).
This is an interesting mishmash of different trellis and training ideas!
This so far I think has been the most comprehensive of all the articles I’ve seen, but it is a lot of words over simplified summaries, so there’s that.
Anyway, I think overall the GDC looks the best, but I’m unsure of my abilities as a beginner to handle it, and if it would fit in the space I want it to. Is it possible to transform a kniffen into a GDC after some practice?
