Trolling Setup Recommendations

[jebrown2]

Hi guys- I am finally getting an initial setup put together for trolling on my boat.  I have the downriggers, but looking for advice on weights, does the shape matter?  How heavy? What about releases?  What has worked well for you? Are there any you would avoid?

I am planning on fishing mostly for trout and kokanee but would also like to go after bigger fish like lakers occasionally.

Thanks in advance for the advice!
