Here are a few Trout Minnows I really rate;
From right to left; Duo Spearhead Ryuki 50S 4.5g, Supremo Baila 50H 5g, Jackson Kanade 50 5g, Jackson Trout Tune 55 HW 6g, Smith D-Contact 63 7g and the Duo Spearhead Ryuki 60S 6.5g.
These are all superbly made lures to cover a few different situations, I feel they excel on streams and rivers and that is what they are designed for, however they are effective on some lakes too.
They're all pretty easy to get hold of aside from the Supremo lures and if you have a good supplier please let me know!
Lastly, here's a picture I quite like from the other evening of a Smolt on the Spearhead 50S;
