I'd agree I did 17 by hand last year, this year have tried electric shears but def more cuts. It's harder work by hand but more satisfying and you def end up with a sheep with few if any nicks, I only nicked 2 tiny nicks in 17 sheep last year. The only reason I will persevere with a combination is OH has limited time to help and Im sure I will get better with them.
I think people assume they have to get shearers in or buy electric ones, and that hand shearing is hard. But in truth its quite easy. It also allows you to leave a small fuzz on the skin if the weather is a bit chilly/iffy if you choose to.
