My older Nolting can be picky about thread. Glide works all the time. I do use the leftover bobbins to sew my binding on with either of my Brother machines and have no problems at all. I don't piece with Glide because it is a polyester and I use the hottest setting on my iron when pressing my seams and I don't want the chance of melted thread.
I wonder why your Janome doesn't like threads it used to do well with. I do use both the ones you mentioned in all my machines and have never had any problems. I do get my husband to open up my machines about every 2 or 3 years and make sure everything is oiled and no threads are loose in the innards. It amazes me how tiny threads can get into an almost sealed machine and the havoc they can create.
