Super impressive performance and like you said, proper breeding. Whilst Olly Murphy is a slight downside, we do at least know that he is likely to be campaigned over 2m hurdles next year. It's rare for Murphy to run his better novices over further. We also know he won't be seen again until next year now.
It's the same bumper as Chasing Fire won last year, but comparing the two performances visually, is like chalk and cheese. The way IB hits the line is incredible. The jockey couldn't pull him up. What he did after the line reminded me of two recent forum favourites (I won't mention their names for fear of hyperbole). I am not sure of course records etc. for Wetherby but 3mins 48secs on soft ground seems quick to me. That was a truly striking performance. I'll be very interested in his RPR. Worth noting the right horse was in behind; Doc McCoy (RPR 104, 107), and he seemed to run his race.
After the race, the performance gets the usual Twitter reception; Josh Stacey gives him the eyes, a Cheltenham branded account calls him Constitution Hill's brother etc. It was therefore surprising to see Denise, Hills and PP offer 50/1 about him for the Supreme. His price won't go out between now and autumn as he's being put away. 50/1 with cash out seems fair to me. Sometimes you have to trust your eyes.
