Why troll for bass?

[bulletbob]

I have a question about trolling stripers maybe someone can answer.. I don't see much about using downriggers or dipsey divers in salt water fishing.. Any reason for that?? Up here thats all that is used for trolling big pacific salmon in Lake Ontario. I realize stripers aren't as deep as salmon generally, but if you are marking scattered pods of stripers at oh I dunno maybe 25 feet down over 30 or 35, downriggers would get you in the zone very easily. accurately and quickly.. Maybe some saltwater guys do use downriggers but I don't hear much about it. Same with dipseys..
I don't like either, but there is NO doubt, that those methods work, and sometimes thats all that works... bob
