I’m going to guess 9 or 10. But as I understand from some of the threads on here, you’re only allowed to count the lines you can see, not what’s been beat off in which case it would be 7-8.
And that’s only a guess, because I dont have any experience. I live in Alberta and here they’re judged by curl for legality, not age. I’m hoping one of the experienced guys breaks it down for us.
