I was using Vittoria Randonneurs for 2 years, but when it was time to replace my back tire, I decided to switch to 28c tires. I opted for the Vittoria Rubino Pro Tech, which are supposed to be pretty durable However, since switching tires, i've had 4 flats, all from road debris. That's all within around a month and a half, compared to the one flat in two years on the Randos.

After changing my flat last night, i decided to go back to my Randonneur on the back (the one that was on the front before) but now I can feel a huge difference in the tire feel compared the Rubino. (bad) Simply put, I like the Rubino ride quality and road feel better.

So, with all that said.. i'm wondering if anyone uses Mr Tuffy tire liners? I've read good and bad about them. Good being that they work, bad being that they increase rolling resistance somehow and could possibly cause flats.

Any thoughts?
