Geffen inserts

Lild09

Ive been reading back on past posts about this brand and I'm all in for getting some sort of insert to double up the absorbancy of diapers once little one starts sleeping longer stretches.  Ive got  3 questions though:

1) Is it worth it to get the newborn size or is it too tiny?  If I go with the regular size, can I fold it down and use it in a newborn cover along with a prefold to boost absorbancy?

2)  Fleece vs Jersey...is the fleece the same idea as fleece liners where it acts like a stay dry feeling?  Ive heard that it pills....will the jersey act just as  nicely as a dry feeling for babe or is the fleece the better option?

3) How many should I have?  Right now my NB stash is basically fitteds, prefolds and BG pockets (old school with the sizing, so I have size S for the new born stage) and of course covers (thirsties, blueberry, imagine...).   As of right now I have nothing to use as a doubler for extra absorbancy and that is the case for both my NB and OS + stashes (mostly BG pockets some size M/OS, Kawaii pockets, Flips with inserts and some GMD M fitteds). 

I feel like I'm asking so much! Any help would be greatly appreciated - this is where Ive become stuck on my journey into CDing.
