For me weight wasn't a huge issue until 50+.

That being said you always need to keep an eye on the weight of the items you are equipping starting at level 1. However, most of the time my monk weighed 30lbs while fighting. At 50+ you may find it easier to reduce weight than to add item AC to get an edge.

I'll add that AC is only useful if you are getting hit and cant just FD out of it.
