I'm not sure conditions do suit the new lion, so i can see a scenario where sir gino wins fair and square (as in new lion completes the race with no mishaps) and the new lion still looks like he could turn the form around.
On one hand he's getting 3lbs, but thats not worth a whole lot if the race isn't ran to suit. Its shaping up like it might be a three runner race. So there's a good chance its very tactical and they go no gallop, which would suit the new lion the least imo. Sir gino looks an out and out two miler, and poniros is a flat horse with good form from 8f-12f. So the race turning into a sprint wouldn't be ideal. They could elect to make the running and set their own fractions to try and make it a test of stamina, but he didn't look to be in love with front running at Newcastle. So whatever they do probably won't show him at his best imo.
I think his ideal scenario in the champion hurdle would be getting a lead and hoping there's a strong pace on. As he's unlikely to get that on Saturday, i wouldn't be writing him off if beaten. As long as he runs respectably enough, even if he's beat 4 or 5 lengths I'd still give him a chance if the race didn't suit him at all.
