They are #8s on the top guns too, I checked with Alan/Beth at A.J.s on that last year. I have been making lures and I can tell you even a #6 is a little big for the smaller lures. Unless you're targeting big lakers I'd stick with the #8s for the top guns and smelt guns and only use #6s on bigger lures (maybe on a couple DBs?). I tested out the action of the lures with different hooks and it made quite a difference. I ended up taking off nearly all the #6s I had put on some lures and going with all #8s to improve action.
The top guns I ordered from AJ's last summer came with size 6 red trebles. The dbs that I ordered from River's Edge came with #8 trebles. I'm looking at them right now.
