You'd really need to ask for owners of specific telescopes you are interested.

I am basing that comment on a Tak FS152 with a 2.7 inch focuser. I tried various flatteners etc and got very bad vignetting.

I ended up upgrading its focuser to 4 inch and it was all good.

Someone posted they had success with a TOA130 and 2.7 inch focuser so perhaps it was a better flattener than the one I used.
