Fielded a five y wing build the other month, five gold sqdrn with autoblaster, btl4 upgrade. on paper they seem reasonable, 40 damage and potentially five dice at range one, one set of three and a set of two from autoblaster. entered a tounament, first game was up against seven z 95 head hunters, with some deft maneuvers i came out of that with a win, i flew them like dogfighters, and didnt worry too much about stress as getting in range one was more important. cant recall my next too games as the dogfight out shone them but i came in fourth all in. i have not used the list since but a club regular feilded a similar build without btl 4 with good results. my next outing with y wings will have three with btl 4 and two without.
