How do I get thicker Biceps?

I think the strength you can build from chin ups directly contributes to curl strength...i utilize them

This is certainly true. As long as you save the chins for back day, there's no problem. But it is primarily a back exercise. Lots of exercises utilize multiple muscles, just like bench press works the shoulders and triceps. But I wouldn't do bench press as part of my shoulder routine.

I'm not disagreeing with your statement. I just see chins as a back exercise that happens to also hit the biceps pretty heavily (as do most back exercises). It may contribute to your biceps' overall size and strength, but the curls you do when you work bi's specifically are more important IMO.

When concentrating on biceps you need to use a fairly close underhand grip and really squeeze the biceps at the top of the movement. Underhand chins concentrates on biceps mostly , overhand chins concentrate on the lats mostly. I do overhand chins on back day and underhand chins on bicep day.
