they were all pretty much the same, some lighter by cutting the ends off (Ritchey WCS)
Many are just Easton EA bars e.g. either Answer Hyperlights 144g/584mm/Ritchey WCS 123g/560mm or the stronger (thicker) Ritcher Prolites ~146g/560mm
PACE sub130 in 584mm should be a fart under 130g,
Syncros are heavier (160g Ti/ 170g Alu incl shim, length ?)
