^^ Completely agree. I have Armadillos on one bike and they are bulletproof, but I do notice the sluggishness of them. I had another bike with the Hard Case tires and they roll very well. I thought they were as fast as non puncture resistant tires. I did notice, like everyone else, that they didn't seem to be very sturdy. I now have the Gatorskins on my main bike and they are the best of both worlds. Fast and have good puncture resistance. I have had them for over a year and they still look close to new. I found mine on sale for about $25. That's about half what the shop down the road was selling the Armadillos for.
