Need tubes for 26x2.1 w/ 48mm SV, thorn resistant.

I've got a mountain bike that has rims that make using the standard (34mm) Schrader valve stems a p.i.t.a. I just flattened both tires riding over blackberry thorns, and am looking for something thorn resistant, like the offerings by Q-Tubes or Slime. Can someone give me a recommendation for a thorn resistant tube to fit 26x2.1 with the longer (48mm) Schrader valve?
Edit: As a fallback, I could go with (std. thickness) Avenir 48mm SV tubes and add some Slime, but I would really prefer thicker rubber, as well.

You could get a tyre with kevlar in as protection, or add another layer of puncture protection between the tyre and tube.

Have you looked at downhill specific inner tubes? If you are using off toad tires, if you want somthing with built in protection, look at something like the Schwalbe Marathon Plus MTB.

For adding products like Slime, you will find it far easier with Presta valves, these are normally fitted on any MTB which is mid range or above.

A better solution, but more expensive is to go tubeless, as these will self (via sealant) heal thorn holes.
