I didn't say they have no future. Poluyanova/Sopot somehow learned a triple. But I'd make a bet on the pairs formed from single skaters, and maybe on several pairs from Velikov's school.
Well, you volunteered pairs who didn’t have triples and then they didn’t make the transition to seniors. What about the pairs who did have triples, and yet never got anywhere? Gainedtinova/Bich had side by side triple Lutz. Unfortunately they were not consistent with their elements and never scored as well as those pairs without a triple, and finally they split up.
