[pct-l] Puff Daddy & Notorious F.L.Eece

[ryan clark]

ok really lame title but i just finished watching the movie Notorious  
with a friend.

so im really trying to get my gear list for the JMT nailed down but  
theres one thing that has been giving me some trouble

Down Puff? Fleece? Pima Loft???

i dont know much about any of them.
does anybody have recommendations /experience / reasonings leaning  
towards any of these.?
whats worked for you and why?

and when it comes to fleece what weight do you use?

cheap alternatives are happily welcomed as well.
