best heat bed sheet for PETG?

I have a Mini and am attempting to print PETG.   The filament isn't sticking to the bed.  I've checked that the nozzle and the bed temperature are corrrect.

Is one type of sheet better than another for PETG?

I use both smooth and textured sheets for PETG.. Sticks no issue.. Best is the Textured from my understanding..
You just need it clean.. and good amount of squish. 

My Mini has: A SuperPINDA + Bondtech Heatbreak + Bondtech Extruder installed...

According to this article, textured sheet should be preferred for printing PETG -because on normal (smooth) sheet, PETG tends to stick too much and is thus hard to remove.
If in your case PETG doesn't stick even on smooth sheet, then I would assume either wrong (bed) temperature or your sheet needs cleaning.

I'm glad I read this.. I've (today) just taken delivery of a couple of rolls of PETG and was planning some models tomorrow; I think your post has saved me from a bit of confusion/frustration... Back to the e-Shop for me!

The textured sheet has been working really well for me and PETG. Sticks nicely while printing, and releases very easily once cooled. The textured sheet is thinner (at least mine is) than the smooth, so you need to adjust your Live Z accordingly. And remember to change which sheet you are using in the menu so the Live Z setting is changed! 

Would be a nice feature for the printer to remind you to check the sheet if you change the filament type. 🙂

I use both the smooth and the textured.  PETG does stick to the clean smooth plate a lot more than the textured or smooth sheet with glue stick on it.  I have glue stick on one side of my smooth and the other side is clean.  I do the same for my textured sheet.  This allows me more flexibility depending on the sticking issues with different plastics.  On the clean textured sheet I always print with a brim.  That seems to help with edges pulling up on some prints using PETG.
