I've recently used Steam a Seam 2 to applique on a quilt and I found it to be heavier than I'd hoped - next time will try the Steam a Seam 2 Lite.. This was my 1st time using on a quilt and I'm anxious if/how it relaxes once washed. Also, I tried a featherweight pellon fusible (I'm out of town so I don't have access to see the exact name/number) but I found that it needed an extra amount of time under my hot iron and was nowhere near as secure as the Steam a Seam 2.
Hope my input is of some help
