That's just my opinion, please don't shoot!
You might think it's a clever dodge to state a fact then claim that's only your opinion, but most aren't fooled. Saying amateurs never run 150-200 km races is a statement of fact [false] not an opinion. To say that effects of tire choice are imaginary is a statement of fact [false] not an opinion. Finally, saying the effects are at best imperceptible is not only false, but shows a lack of awareness of what testing is able to measure these days. Just because you can't conceive of making these measurements doesn't mean others can't. They can, and have carried them out.
