Both are good Nelson, cambered and straight bar. They are just different which is good, why not do both to mix it up? There is not really a right and wrong way. There are obviously VERY differnet shaped bis. This is largely due to genetics. Sergio had extremely long bicepts, but not very high. Arlnolds were noted for having a very high peak. Larry Scotts' were "full", (long and thick). Obviously because of this, certain exericses will be better for certain people.
They say to really make your bis grow that you must make your "inner" bicep grow. By this they mean working the front head of the bicep with the point of insertion under the elbow.
Try the "One and a Half" method. Try these ... use an EZ curl bar and sit at a preacher bench. Bring the weight up half way, slow and controlled (should be straight out in fromt of you), then slowly lower it to the starting position. They bring it back up through the full range of motion (up to your chin), then slowly back down again. COUNT THIS AS 1 REP!. rRepeat. Up half way, down, up full way, down, ... up half way, down, up full range, down .... etc. etc..
