there are a number of different fusable battings, all with their own properties. some work better than others just like some batting works for this but not so good for that...some people love them and use nothing but (and not all of them are stiff...some are fluffy as a cloud)
some people do not have luck with them. none should gum up your needle any more than any other fusable that is 'stitchable'. if you are interested in trying them out, pick up a small one you find available and make yourself a tote bag or something..see how you like it.
