with so many brands out there, you probably have to do some trial and error and refer to manufacturer's guide line. even the extrusion profile is different between manufacturers.

for example, delux with its own polyroof X25 uses it quite successfully from the examples i saw. no reason to see why such similar products are having quality issue in this era if precautions and install techniques are taken correctly.
