I'm working on some edits to a paper under review with coauthors. Comments include advice that a better writing style be used and awkward wording be fixed. Coauthors are comfortable and expressive in English as a second language but to me some sentence construction and phrasing is awkward and un-smooth and it sometimes takes me a while to see how sequential points connect. I'm not a particularly good writer myself.
Coauthors are readily amenable to grammar and word order fixes much but less so to paragraph rewrites; "no, that's now how I want to say it".
I sense that further suggested rewrites on my part might not be the way to go, but "objective" advice on writing might still be welcome.
Short of a professional technical writing service, are there dispassionate tools (e.g. websites or programs) that tackle paragraph-scale technical writing construction, and do academic journals every recommend any of these or similar? What other solutions might exist for this situation?
