Suggestions for improving my current strength / mass routine

My Current Routine is the following.....
 
Goals : strength and some mass
 
Day 01
A1 Squat 5x5
A2 Bench 5x5
Row 5x10
Seated Pin Press 5x10
 
Day 02
BB Incline Press 5x5
Incline Dumbbell Row (1 arm) 5x10
Barbell Step Up 3x10
Fat Gripz Barbell Holds 3 x max time
Fat Gripz Overhand Bar Hangs
 
Day 03
One Arm Overhead Press 5x10
Sumo DL 5x5
Gripz Pull-Up (25 reps)
One Arm Floor Press 5x10
 
After week 4 deload by dropping  5x5 -3x3 and 5x10-5x5
add weight from weeks 6-8
 
Now I've done two cycles of this routine with slight variation in exercises each time.  I quite like the simplicity of it (not working with percentages).  Just not sure where to go from there ?
 
Might change the exercises again but keep the format.  Bench is the lift I most want to improve, so want to keep high back and triceps volume.  Considering adding some speed work but not sure where.  Grip I also need work on....
 
Thanks

Have u considered rotating your sessions with light (3x12), medium (4x8) and heavy (5x5).
 
ATM i'm doing this with an A and B routine so the same session comes around every 6 sessions.
 
for example,
 
A - light
B - Medium
A - Heavy
B - Light
A - medium
B - Heavy
 
The rouine's are,
 
A
squats
bench
rows
 
B
Deadlifts
OHP
Pull ups
Dips 

I've done a similar routine but instead of rotating the sessions I stuck with each rep range for a month then changed the days around.  I find that I need to stick with a rep range for a few weeks before I change it.  Since it often takes a couple of weeks to select the right weight for that rep range....
 
Do you add any other exercises or just the compounds ?  I've done pretty much the same exercises as yourself for a while.  I think it's a great template...

yeah I add the odd isolation when I see fit, usually in light days when my body'a less battered!

If strength is your primary goal have a look at;
 
Stronglifts 5x5
Starting Strength
 
Both focus on compounds and continuous progression, both work very well.

I've done several cycles of Stronglifts Advanced.  It was good but squating 3x plays havoc with my joints.  Starting strength I guess is similar.  I have the book at home so I'll have a reread :)
