Overall (most Siser products in general) install at 305deg and they are almost all hot peel for super fast production. Hot peel also helps a lot with multi-layered work where your shirt has a tendency to shrink between layers so faster peel lets you throw the second color on before that takes place in some circumstances. Also regular Easyweed in available locally if I have an emergency although I order most of mine in from USCutter. Quite a few of the stahls line are on a frosted carrier which is trickier if you accidentally pull up a letter (Not sticky). I don't do much of the fashion style application like glitter or moda, my market is mostly in the durable workwear, high school parent shirts and team jerseys.
I don't have an issue with the stalls line-up. Thermo Film although thick is a really durable product and give almost a rubber feel. Fashion Film and the Premium are great products too similar to Siser Stretch and I have used many many yards of Super Film (cold peel bleh) because it's about the only stretchy option for nylon volleyball jerseys.
