Yes, there are so many other aspects to consider, as well as horns, aren't there.
We do the same, any obvious problems, castrate and into the meat queue. The rest (plus any we couldn't catch at banding time
) grow on to 16 months, at which time we decide if they're meat or worth trying as sires. We tend to run any promising ones with a couple of ewes before we sell them as breeding stock, to check fertility or any other breeding problems. Some years we get no keepers, the most we ever had, back when we had a much bigger flock, was three keepers in one year, of the multihorned, which we found amazing
No wonder it's hard to find a good m/h tup !!
