Actually the slots are for water to get by. But it makes sense when they are gone to replace the pads because they won't work as well when wet.
Why would you use aftermarket pads if you're happy with stock pad performance?
Most people find Kool Stops work much better than stock. I'm sure the OP will find that with Tektro.
They should last for a few years.
Yep. I probably have 20,000 miles on one set and they still work fine.
