As a big Caudabe Sheath fan, try using it for a little while without switching cases on and off. There's a reason so many people on here like it. The texture is an acquired taste, but at least for me once you acquire that taste it's hard to go back to anything else. I came from an Apple Silicone case many years ago and the texture was really different from the tacky-ness of the Apple Silicone case. But, the more I used the Sheath, the more it wore in if that makes sense. The texture always seems to wear down to a nice, pleasant feel after some use.
As for the size and weight, I never really had any issues with that. It's like an ounce or so max? Comparing its weight to the Apple Silicone case is like comparing a feather with an even lighter feather. They're ultimately both feathers, lol. And this year I was pleasantly surprised because the 15PM with the Sheath feels noticeably lighter than the 14PM with the Sheath. So for me, the combo feels plenty light.
