Need help choosing a pack

I’m an intermediate climber in the north cascades. I’m looking for a do it all pack for both climbing and ski touring. What I want for in a pack is external ski carry loops, external rope carry (which could be interchangeable with the ski loops on some packs I think), dual ice axe attachments, waterproof or good water resistance, and about 35-40 Liters of space. I don’t plan on bringing more that 20-30 pounds with me at a time. I’m currently looking at the hyperlite prism 40 (which is perfect expect for the price tag),mountain hardwear alpine light 35 (good except for the waterproofing),arctyrx alpha fl 30 (has mixed reviews and apparently isn’t comfortable at all). I’m wondering if it’s worth it to save for the hyperlite pack, or if something else out there fits the bill. Thanks.
