Swap the Very Wide Grip Pullups for Normal Grip pullups. No point doing Pullups and Pulldowns IMHO.
Hams = SLDL / Ham Curls / Box Squats
No point doint both Mili Press and Shoulder Press IMHO.
4 Exercises for chest might be a bit much.
11.5st - you might as well start a log dude
3x8-12 is fine. Do different rep ranges if you like.
I'm really not a huge beleiver in rep ranges making a massive difference. As long as you are working the muscle as much as you can thats fine.
Be it 3x8 or 8x3.
