If your trolling for white bass, how do you get the lure down to a specific depth say 30 ft or 40 ft deep trolling speed say .8 to 1.8 mph. I want to grab some trolling weights like torpedos in 3 oz - 5 oz I didn't know if anyone on here had any experience with trolling with those weights. I would imagine putting a 3 oz weight with a 4 foot leader on it with a meeps or sassy shad or pet spoon on the end would do the same as a pet/spoon type set up. Any suggestions on what you do to get into that depth, what troll speed, and what lures you recommend for best results?

I've successfully trolled for hybrids in my hobie outback.
For hybrids I recommend using paddletails on jig heads, I generally adjust my trolling speed and use 2oz jig heads to get them deeper. On a typical trolling day I have one heavy jighead running deep, a lipped diving crank, and a rattletrap.
That way I cover all depths.
When releasing line on the Paddletail+Jighead I stop make sure I'm on bottom, pickup my speed on light drag and keep stripping my line until I'm trolling 1-2feet off bottom. then I release my other lures.
Not the most informative video, but you might enjoy it if you're into trolling, we caught 100+ fish that day

You can use a 6" or 8" Ronrig to start with. They look like a small school of shad swimming together. You also want to get the clip-on weights that come in 2 oz to 6 oz sizes. Clip the weights on ahead of the rig and let line out accordingly, about 60 ft. to 75 ft. usually. It's best to start out with this setup in a lake that doesn't have a lot of trees. On a muddy bottom, add enough weight to let it drag bottom occasionally, at your desired depth to make sure you are deep enough. If you continually drag bottom, go to a lighter weight or speed up a little. After you become accustomed to using this rig, you can get the larger rigs like the Transformer, which has 9 jigs and several willow leaf blades also. I'm sure Ron would love for you to start with this one, (he can sell you more this way)but it is very expensive to loose. lol. Not really. Ron wants repeat customers, so he recommends folks new to his rigs use the smaller versions first. Sorry for the long post, I've been drinking.
