Ideally you would want more than 10k up top if you are considering BC. 20K or Gortex. Although I am back on 10k as I had trouble with my AK jacket (kept tearing) and when I was looking the company (it was warranty) did not have 20k.
I only notice it if its raining or if its a really really hardcore day weather wise (high winds, wet snow)
Bottoms you will be fine with 10k
Oh and there will be an option for insulated or shell. If you don't do much spring riding I would go with insulated. Otherwise get a heavier shell and layer underneath for the colder monthsl
Hope that helped.
