Dockboy, I prefer round casting reels for trout trolling. Personally, I use the Shimano Calcutta CT50B(7.8 oz.)for light trolling with 6-8# line. I think this is the best light trout trolling reel avaiable. Although, this reel is twice as much as you would like to spend, I would consider it. A good medium size reel for $100, although a couple ounces heavier, would be a Okuma 150.
