durablity is the only way to go for me, if ita not going to last 5yrs, forget it, i wait for a month b4 i buy anything and do alot of reaearch and thinking b4 i buy anything, dont want to buy anything and throw it on a bin. yes 500d is heavy but thats why i have a maxpedition pygmy falcon 2 pack, only 3lbs fits everything i NEED with a lil extra room. its a bag thats always with me so if i wanna go camping, i dont have to pack up the stuff cux its always ready to go 24/7. but i do have to wait for my buddies to catch up.
