We used Jigsaw and had about 10 calves off him last year. They were consistent peas-in-a-pod with a very maternal look. Good bone, lots of thickness, and not puddy. We sold every one we had, with the exception of a set of twins, as show calves, including the heifer that was Reserve Champion Prospect heifer at the Canadian Agribition. We were really pleased with how they turned out.
If your first calver has already calved with no issues, I would not hesitate to use him. If she is being bred for her first calf, you might want to wait a year. Ours were thick when they came out too - everything between 90 and 110 pounds (consistently - but that's also taking into account a Canadian winter).
