Pack weight depends on the person... if you feel you can handle that weight
then take it
most ppl find out on there first trip they packed way too much
and end up cutting alot out for there next trip
for me if my pack weight gets over 15lbs i get cranky ...
my summer base weight is under 7lbs .... my 3 season is around 8lbs and winter is 11lbs
but i'm a UL guy.... not everyone would be able to do 3-5 days with my load out
i say hike with what you have and if you feel it's too much... come back make 3 piles of gear... one pile is the pile of gear you used ..include your first aid kit in this pile
next pile put the gear you used one or two times
next pile is the pile of gear you didn't use at all
take the pile you didn't use and put it away.... next goto the pile you used one or two times and find out what you can live without or replace with items that have more then one use ...
i do this after every trip.. even to this day i still do it and it works
