I was thinking about your question this morning, and I saw that there were no replies. SE 3D Printing is quite a small site and there aren't an awful lot of regulars here - but there are just enough who can give great answers, but not everyone ventures here, into meta.
I think that you should ask the question, it does seem on-topic. If it is well presented (without typos) and has the necessary detail, then it should be OK. It is usually only very poorly worded, poorly formatted and overly broad questions, where little thought and research has been done beforehand, which are shot down in flames... :-)
Looking at your Reddit post, it seems ok, but it could be worth relevant quoting parts from those links that you listed (as links die over time and the information that you refer to could be lost), and show why or why not, you think certain options may or may not be suitable. Your question could also appear to be opinion-based or broad - so it could be better to narrow down your question to a point or two (or three).
If it does end up getting closed, which hopefully it won't as you do appear to have put some thought into it, you will be provided with guidance as to how to edit and improve it and make it more suitable for StackExchange.
I wouldn't worry too much, even the best of us have bad post days sometimes... it's not a big deal :-)
Also, think about it this way, the time that you take formulating and crafting your question will be well spent as it should help clarify your question in your own mind. Often, I have found, whilst writing and clarifying a question, that I had actually mis-understood the whole issue in the first place, and sometimes re-working a post can help me find my own solution (especially when using peoples comments to adjust the original post), or at the very least, help me get my head around the issue.
TL;DR - Don't over think this, just post your question :-)
