I think it should be about like normal, 10-15 SVs. I would definitely consider waiting for him to drop down, though. I agree with ~25 HVs on average once he's recruitable.
Sidebar, SVs used to pull down don't "count" for as much as normal SVs. If you believe 3 SVs=1HV normally, then it's probably something like 10 pulldown SVs=1 HV.
