Summer caps LFGSS

My list consists of a 'non-original' i guess, they might be coming from a different manufacturer than before (I don't know who produced the old ones) would people prefer if the caps were elasticated well so one size truly fits all or would two types of small/medium and medium/large caps be favoured?

I think (correct me if I'm wrong) we've established that the caps are coming from Velocio's connect.
