New routine check

Hello fellow MT members
I am fairly experienced in weight training, having good gains over the last 5 years or so. Due to a new job etc I have been forced to cut down on the gym to 3 days a week. My new routine focusses mainly on compound movements. Please can you comment on the routine, which is:
 
Tues- Push
Bench press 4 x 6-10
DB incline bench press 4 x 6-12
DB shoulder press 4 x 6-10
Barbell behind the neck press 4 x 8-12
Skull crushers 4 x 8-12
 
Thurs- Legs/pull
Squats 4 x 6- 10
Leg press 4 x 8-12
Chins 4 x to failure
DB bent over rows 4 x 6-10
EZ curls 4 x 8-12
 
Saturday- Push
same as tuesday
 
Then the following tuesday will be legs/pull etc.
 
Each workout includes 4 sets of sit ups/ crunches at the end.
 
Let me know what you think!
 
Thanks in advance

Why not just do push/pull/legs split over the three days?

because I don't like training muscles directly once every 7 days. From my experience I don't think that works best for me and I have had my best gains in the past by training each muscle directly twice a week.
