Switched Routine, but need some help

[tzan]

I need some help. I've decided to switch up my routine, paring opposite muscle together, but I can't figure out what the best order would be. Here are the muscles I want to work together:

Chest/Bi's
Back/Tri's
Shoulders
Legs

This is how I originally had it:

Day1-Chest/Bi's
Day2-Legs
Day3-Off
Day4-Shoulders
Day5-Back/Tri's
Day6-Off
Day7-Repeat day1
...The problem with this is I don't feel I give my rear delts and traps enough recovery time between shoulders and back days. I think I might also want to take another rest day in there so I workout each muscle group once a week instead of every six days. What would be the best way to arrange these?? Please keep the groups paired how I have them. I have one in mind, but am curious to see what some of you guys come up with.
Thanks

I'd add shoulders to back or chest day. Then add forearm excercises to the other day. Makes it a three-day split and you'll have your recovery time taken care of.
