Yeah, for "I could probably make it without studs, but would like studs to be sure" riding, the A10's seem like a decent tire.
I like my Schwalbe Marathon winters - pump them up to 60psi and I only lost 1mph at 35c versus the 28c non-studded tires I had on the same bike right before that. They also have a cool stud pattern where at higher pressures the outer row of studs doesn't contact the ground, but at lower pressures they do. However - they also cost about $80/tire, so like twice as much, so A10's are certainly cheaper if you aren't ever biking on sheer ice like I am. :-)
Thanks for your thoughts on the tires! Would be curious to see what you think after you have more time with them, to.
