try straight arm pushdowns. I had lots of thickness thats what started making them wider.
Not a bad idea. It's basically a pullover motion. Include a pullover motion along with chins and/or pulldowns in each workout, for width. The best is a pullover machine if you have one, or do dumbbell pullovers on a decline bench or the straight arm pulldowns on a cable.
Also try some pulldowns behind the head. If you want to minimize shoulder probs from them, you can always do 2/3 ROMS, leaving out the bottom of the motion.
Chins and pulldowns can be done each workout, or do more of one of them then switch to the other some of the time. If you do them both in the same workout as you're doing now, there's no reason not to do the same number of sets of each.
Sometimes also superset a chin or pulldown motion with the pullovers. Also try varying the grip width on chins or pulldowns, and try changing the handles. Try a medium grip, which is great for width, and try different grips-neutral, hands out, etc. Also try using a triangle close grip attachment sometimes for chins and pulldowns.
