I started doing pull ups with the C&P, now the Giant has its days and i'm just doing warm ups before doing them and left the pulls for other days (I normally recover well from one day to the other so no problem there). Having said that, the rows will restrain your performance when a certain volume is reached, even now if you just do the C&P you will reach more reps/volume if you leave out the rows for some other time.
Regarding longer term, I've been into the program 8 months or so and for me its ok, I started cleaning and jerking the 24 kgs bell and now I completely own it adding the 16kgs as well, I could work 1.0 with the 34kgs+24kgs but I'm still waiting. My reps range even if i dount count it everyday is somewhere in between 60 to 100 reps per session, for me thats the sweet spot, I keep gaining strenght, my conditioning is good and have hypertrophy results, if I add pull ups in between I couldn't manage that number of reps and I'm sure I wouldn't recover and perform well the c&p.
If you split up both works the volume would be ok under my opinion.
