Which Upper/Lower Routine

I have come up with 2 upper/lower splits and was wondering which one looks best. My goal is size so I will probably be in the 6-8 rep range for a while. I do eat alot 3400-3800 calories per day. If anybody has any input it would be helpful. I was going to do Bill Stars 5x5 until christmas but I really like lifting 4 days a week.

Why not use the first one for four weeks, then switch to the second one for four weeks?

Also, I would vary the rep ranges within the workout or within the week.
