In the 15-18kg range.
The most important aspect of any bulking program is eating for it. Training 6x a week was perfect for cutting. And re: joints - taking about 15 fish oil capsules a day is something I can't recommend enough. Glucosamine is also very effective for some (I used to get more out of it but fish oils work a lot better for me - took some time to figure this out).
Back to bulking though. You (anyone) won't grow a damn if the food input isn't match the time and energy spent training. Doing a 'slow bulk' or 'clean bulk' is really not a reality for 95% of people. The minor genetic differences that separate elite athletes like Phelps and someone as energetic and massive as Ben Wallace (former NBA C/PF) used to be make a big difference in terms of the muscle : fat ratio. Obviously in terms of gene expression, it's a minor detail and nothing like being predisposed to breast cancer or male pattern baldness, brown hair vs blond vs red hair etc. But whether you're gaining weight at a 51:49 rate or 60:40 etc (just spitballing the actual ratio or %'s) means that proper bulking and proper cutting are the only real ways for most of us to go about it.
Gain 10kgs, lose 4, probably a net of 5kgs LBM (increasing bone density is also a form of LBM, albeit not the same #'s as muscle gain). Of just about everyone I've seen trying to 'clean bulk' the only people to successfully do that are professional athletes. Take a look at the transformation of Michael Jordan from 85 - 92/3, Alonzo Mourning from 93 to 98, any # of AFL stars (Australian football). If you aren't in the genetic elite (and you may well be one of the 3-5%, SOMEONE has to be

), then it's going to work better if you bulk properly, then cut properly.
Re: training 6x per week, my A-B program was roughly this:
A-
2x Weighted Dips
2x Chins
2x Squats // Leg Press
2x Shoulder exercise (Military, DBell Press - standing or seated, whichever)
1x Bicep exercise
1x Tricep exercise
B-
2x Incline // Flat Bench
2x Bent Barbell Row (Pendlay)
2x Deads (have to do them after the first two exercises or there's nothing left, also properly warmed up)
2x Shoulder
1x Bicep
1x Tricep
Getting to the 2nd fortnight of heavy weights, I'd only really push one of squats or deads. If pushing Deads, I'd do Leg Press for that cycle. I like the Leg Press a lot, it works my quads a lot more than squats do (body proportion at work).
Other things I've experimented with a lot are:
-Cluster reps: love 'em, great for strength at the end of a cycle
-Negatives: great for Bench (or any 'press' exercise), less so for Chins (I find the arms take too much load at the start of the 'pulling' actions)
-'Bouncing Negatives' at the bottom of chins - really hard to explain, the Uni's gymnastic coach taught me: meant to work your technique a lot, building the 'explosiveness' that all 'experts' say they've nailed. Not really sure how well they worked.
-One legged squats - these are the nut high, really hard to do them weighted and safely though. Definitely need the fully equipped cage for that.
