In my opinion, 1lb of cara-pils is way too high with 1lb of crystal. You could probably get rid of it completely...
I'd move your 0.5 oz 45 addition to 60 (so 1oz @ 60), and your 0.5 oz 30 addition to 15 (so, 1oz @ 15).
I just prefer a 60/15/5/0 schedule for my APA's generally.
Looks good. Chinook/Cascade make a good combo
