Just bought a new bike (early Christmas present!) and it came with Conti Gransport 'race' x23

My bike (and my sons) have ran Bonty hardcase tires with pretty good results. (his 700x25, 2 flats in 3 years - mine 26x1.5 slicks on mtb, 2-3 rides per week 4-5 hours a week weather permitting)

I basically drive fairly nice roads to blacktop trail system, I dont do any crazy cornering, althought I do like to try to go fast in a straight line - I have never carried tubes or inflator yet

I am debating on
1) put Mr Tuffy liners in my stock Conti gransorts

2) Run stock tires as is

Or sell stock tires as take offs
- and get something like Bonty hardcase again or Conti Gatorskins, etc

Thanks in advance
