I could not agree more with this - cutting is easy I find - its the mental thing thats hard but once your couple weeks in even that goes. Bulking is a different beast - start with the low end of your calories just over maintance and then work from there - really just an limit weight gain to 1-2kgs per week if possible.
But I totally agree with Bazz - the mental aspect is nearly harder than cutting - "Oh I am bulking, I can eat whatever I like" nek minute - weekend is gone and you have gone from 105kgs - 110kgs and then you need to do the fuck around to nearly drop cals below maintance to fix it to get back on track.
All in all in my 12 yrs of lifting Bulking has always been harder than cutting - as I said just low - work your way up....
