Definately on the right track here!!
What you say about the pouch can be done, but you could also buy another one..
You also need to modify the ab-plate, TD's got 3 buttons instead of 4.
I can't quite see what kind of shoulder straps you got there bro', but if they are still of plastic replace them by canvas ones.
The pack also needs some work but you can find alot of tips and trics over here on the boards to get the right look.
Keep up the good work!!
