LB, read my response to your complimentary thread on the strength forum. 'Bulking' and 'cutting' are not valid nutritional or training principles.
2grams of protein per kilo of lean body weight will be be sufficient for all your training needs (maintenance and growth) but you could go as high as 3grams if you feel better about it psychologicaly and you have the money.
To know your lean body weight you must have a body composition test, carried out by a professional (home bodystat kits/ shopping mall coin operated gizmo's are not accurate).
As for overall energy intake, it needs to be in balance, the concept of 'bulking and cutting' is just yo-yo dieting whilst training. It doesnt offer a helthy long term solution to your goals.
