Pulling too much, but ignoring the dips?

Ok, for the first time in my life I can do more pull ups than dips. I think having a pull up bar in my home and no corresponding dip equivalent has really biased my training to stuff I can do while hanging. And I guess doing the rings (mostly hanging or straight arm support-type skills) is also biasing the type of strength I'm developing. I did weighted pull ups and dips again yesterday. I can do 70lb weighted pull ups, but I don't think I can do 70lb weighted dips. Plus, my lats and back still feel pretty fresh whereas my pecs are a little sore this morning.

I find it amusing that most people who strength train are too pec-centered in their training. Just look at all the meatheads in the gym doing way too much bench press. I used to overemphasize benching, too. Then I got a shoulder injury and listened to my PT about balancing out the strength in all my muscle groups. I don't think it's possible for me to develop a strength imbalance with all these pulling exercises, but I'll need to check to make sure.
