David, if you want to use 130lb and a PR knot, go with Varivas GT and perhaps no more than 170lb mono leader. I use a 200lb mono leader in the YGK Gailis which is ok but I am going to go back to 170lb. You can always attach a bite leader to the end if need be but really, I wouldn't wory abotut his unless you're chasing huge GTs.
A bimimi/twisted leader is fine. It is only when using stickbaits in very clear water that I think it is advantageous to use a single strand leader. You could of course simply put a single strand bite leader onto the end of a twisted leader.
I'll get around to a trip report sometime!
