Berezinsky, Hnatyk and Vilenkin showed that superconducting cosmic strings could be central engines for cosmological gamma-ray bursts and ultra-high energy cosmic rays. If such a mechanism proves efficient, a (LIGO, VIRGO, LISA, TIGAS) detectable cusp-triggered gravitational wave burst should be released simultaneously with the \gamma-rays surge. Since photo-meson interaction triggers \nu-flashes from \gamma-bursts, its cosmological time-delay respect to both radiations may prove useful to put unprecedent tight bounds on the neutrino mass spectrum, whenever a detection in coincidence could be pursued. It may consistently prove or rule out the quoted model as the hidden mechanism, since a bursts matched evolution (time variability of spectra and duration) is expected.
