910 is horrible stuff. Got a roll - never been able to do anything with it.
That said it's made for heated enclosures which I don't have :-)
Get a sample. https://globalfsd.com/
they have a us warehouse.
And yes that's my review from a few years back :-)

The problem with most taulman nylons is that they just tell you how amazing it is but never that it's designed strictly for heated enclosures. So you end up buying it under false pretences. Got a couple taulman rolls around that I've never had any joy with.

The 645 is a different beast entirely, prints as well as any nylon (mymat from italy is the best) and doesn't need heated enclosure.
Got some left somewhere.
