I've heard those TKCs are very difficult too. Perhaps they have a particularly stiff sidewall.
I agree that making sure the opposite side of the tire is pushed well into the rim well is the key. I've only done a few changes - the first couple involved a lot of effort. The last one I relaxed, took my time, lubed it really well with dish soap, and made sure the tire was in the well. It took just 11 minutes to swap tires - not just tubes, and I only used stubby levers. I guess I got smarter, not stronger.
Nice to know I can outwit a rubber doughnut...
