Please Critique Routine

[trek4]

I'm 24, been working out off/on for about 3 yrs. I'm 6' and 175 lbs and am not using any gear. Here is my routine that I've been using, how does it look? I don't train on specific days of the week, but I follow a 6 day cycle. I usually alternate b/t barbells and dbbls each cycle on the exercises that are applicable. I've been using a rep range of 8-6-4, but I've hit a plateau so I'm going to switch to a range of 12-15 for about 3-4 weeks. Please let me know what changes would be beneficial. Thanks!

1) Bench
Incline/Decline (Alternate each cycle)
Flyes
Close Grip Bench
Skull Crushers
Weighted Dips

2) Squats
