Darkoz, I asked Sticky a similar question once before when he posted pics and he replied that it doesn't have to be only about the numbers. I thought that was fair enough at the time because most of us keep track of both sides of our progress. I was only having a sneaky dig at the time anyway because there is a bit of a strength superiority complex around here and it used to shit me. I have since learned to live with it and keep my mouth shut most of the time.
Sticky, if I remember correctly you had to drop weight from around a hundred for your comp last year so the 13kg might not be that difficult for you to find considering your current bodyweight is pretty low. What is your plan? Are you going to train specifically for some added size or continue training as is and basically just eat for the additional mass?
Every time I see your pics I am amazed at the weight that you can lift. Your back is phenomenal but it looks like you have had someone else's arms grafted onto it.
