First of all, I just want to thank everyone who has helped me before, offering their experience and wisdom in questions that often cannot be sought and anwered any other way. You, collectively make a wonderful resource for the rest of us. With all the choices out there, how in the world does one have any idea what slip-ons to consider? Is is simply being lucky enough to have the right mix of freinds with a diversity of their own installations and opionions - or can it be more technically assessed than that? I mean, you can't try them on for sound, like going into a fitting room and trying on a pair of pants before you buy them. I would love to hear what helped make YOUR decisions for YOU.
