I do not think that the spanish standard calls for a high tail angle.The new boy has sickle tail in the back but the tail angle is better. The comb is better and the body shape looks better.
Start breeding with the new boy. You will not get chicks from him for two weeks and some chicks will still be pedros for about 30 days.
There should be a lot of new cockerels to choose from for next year. Remember that the hens also add quite a bit. Maybe work with them for combs and tails. Do you mark the eggs and then bad the chicks so that you know which chick came from which hen? Keeping track of that will help a lot.
