RST Rift 2 piece suit for $749 with a new RTS helmet (could be the trackday/emergency helmet)
AGV Sport Blade 2 2 piece suit for $590...
both are zip together and so would allow me to use the jackets alone but the AGV sport pants don't come with knee sliders...
not neccesarily a deal breaker but something to think about...
the RST suits are the ones they hire out at EC and they fit me very well and allow for good movement so i'd be buying a known product...
i know there may not be much you knwo about them but maybe if one or two members have had experience with AGV sport leathers then that would be helpful

cheers
