Default Contemplating CAM change?????

I have been thinking of changing Cams and Flycutting the pistons to suit a large duration Cam, which Cam should I go with to get noticable gains? Keep in mind that I road course this car and that the Car weighs 2900#'s with me in it. I also just purchased a ported TB and a Fidanza aluminum Flywheel to add to the combo.

93 Mazda RX-7
01 LS1, T56
30#fms injectors
LS6 intake, 241 heads stage 1 TEA Milled 0.030, stock valves
Cometic 0.040 Head Gaskets
intake exhaust
.100 71.0 52.6
.200 136.4 109.2
.300 207.2 159.1
.400 249.1 203.8
.500 280.1 230.8
.550 288.5 239.2
.600 291.1 245.2
CAM- Futral F6 226/230 .575/.595 112lsa
ARP rod bolts, and stock TB.
LS2 timing chain, ASP UD pulley
1 7/8 LT's 2.5in true dual exhaust

Put down 418rwhp 384rwtq thru cats, steel flywheel, steel driveshaft, and a rough tune. Since then it has been retuned on the street and it is definetly making more power.

What CAM would you go with?
