I don't fly my B-wing's out too far, especially without boosted Comm's I let the enemy come to me, I set up a "Bomber screen" at around the middle of Blue Die range so when anything comes in at the whales, they must face the B's first/at the same time.
Also if I knew I was going against that list, I would run opening Salvo, Fleet Ambush and Superior positions. Salvo helps me add blues or blacks to the whales first shots, Fleet Ambush splits up the ships at least a little and depending on how deployed I could get in to them first or second turn with Whales + B-wings.
Superior is the best case pick, as you can then see which way you want to point your whales to be able to speed 3 Kite the Raiders, usually they end up in a semi conga line if you can sweep around the board at the right time.
I get the Raiders are there to draw fire/be blockers/extra damage and activation order for Demolisher as Demolisher is the key to the list, I have always thought it was a little too good for its points (title and the base ship) but that is just my view, it's even better now with the upgrades from Wave 2.
Also the reason I said XI7 is because going in to a a tournament I would not know what lists I would be facing, so it is there for when I do get vs ISD/glad spam/Other Rebel list. It is bad to build only to counter this list.
Also as fragile as it is being a Neb, I'd be tempted to run a Neb-B Salvation + Raymus + TRC. Minimum 2 damage, max of 8 or 6 + accuracy before tokens, even better vs the Raiders because odd's are the crit will get through as well. - However Neb's have the unfortunate habit of wanting to fly directly at the enemy, which is exactly what this list wants you to do.
