well, here are a few things I have done. I jump all over the place as to what exercises I like. If I'm hurt or stalling out I will change things up immediately. I only do the body parts on there specific days though.
I know my splits are different than yours of course.
I do chest/tri's one day (I do close grip bench after heavy bench myself too)
I do back/bi's
I hit the gym 5 days a week and have 4 workouts. I have no specific day to do any of the workouts. It all depends on what I see when I walk into the gym. If all the benches are taken I will start on my back/bi's. That type of thing. I will say that imo bi's and tri's can be doe 2x per week. On my off day I will throw in some kight supersets with bi's and tri's. high reps lighter weights. I try not and do traps on the workout b4 legs if possible. I've found that just supporting the heavy bb taxes my legs for there dedicated workout. I also no that i am prone to porking up over the weekend so I try and not do back on Monday (pull-ups are harder witht that extra weight)
For me the optimal week would be\
chest/tris on Monday. Legs on Tuesaday, Back/bi's on Wed, Traps/shoulders Thurday, and then on Friday mainly cardio but I will do my bi's/tri's superset thing on Friday also. Sometimes I will fill in with some of the things I had to cut out though due to time constraints during the week.
I think it's important to realize that you don't have to do the same exercises each time you hit that body part. yes, if you are trying to judge gains it's important, but for growth I don't think so. Just my .02
