you just need to get good high quality tubes like, Continental, Specialized, and Vittoria. A thorn resistant tube is heavy and most are cheaply made, sure the seams may not rupture but that's only because they're very thick. And like another poster said thick heavy tubes will make your bike feel sluggish. If flats from debris are causing you issues a thorn resistant tube is the last line of defense against debris and is almost useless in that department, instead your tire is the front line defense against debris, so get a good flat resistant tire instead of a fat heavy tube.
