With the .490 round balls I am using a .015" patch. When I order my .54 barrel should I use a .530 ball or .535 ball because I am planning on using a .015" patch because Ive got a lot of them?

.015 is what i use in my 54. i have to double patch because they get torn up some some pitting i have in my barrel.

Where are you getting this barrel from? Is this a Green Mountain Barrel?

Yes planning on gettinga green mountain barrel. .54cal 32" 1:70 twist, but also considering just buying a lyman great plains .54 with 1:60 twist

I'd go with the .530 ball

The tolerance is big enough on these barrels that the best way to deal with that is to try both the .530 and the .535 I have ended up getting the best accuracy from all but one of my .54 hawken and renegade rifle with the .535 and a 18 thou. ticking patch. Lee
