Crankbait Depth for Suspended Fish

[macgyver]

I've been working crankbaits a lot more this year than any other time I've fished. Mainly because the fish have been suspended a lot more with the vegetation being sparse this year. I've had very little success, even after trying numerous techniques. I have had better luck with spinnerbaits this year however. Here's my questions.

1.Once you find the suspended fish at a certain depth(by your fish finder), should you select a crankbait that goes deeper than the fish or just above them. I assume ideally you would like to go right through them, but I am talking about selecting the right depth of crank bait. For example if the fish are suspended at say 11 feet, should I work a D-10 or a D-12 or something higher or lower.

2.I also would like to know which cranks in your opinions are the best suspending cranks. I prefer ones that rise up a little or suspend, even though I do like the lipless cranks, but they have to be cranked almost constantly to keep from dropping too far.

I've been using the bottom digging technique a lot with 0 success. Obviously I'm not great at cranks, but I feel it's one of the areas I need to work on to become a well rounded fisherman. Any suggestions are greatly appreciated. I don't want to be limited on what I feel confident in to use.
