To understand why Bullet Fies are more effective on educated trouts, we need to understand what kind of trouts we are talking about here. We find all around the world two different behaviors of trout that are getting educated because of high fishing pressure.

In any case, an educated trout will be selective on its food. Some trout flee at the sight of the fisherman on the bank, while others remain in place and continue to feed.

To develop the range of Bullet Flies nymphs, we were fishing 3 American rivers with high fishing pressure, namely the Frying Pan River, the South Platte River and the Green River.

In all three cases, it was noted that brown and rainbow trout remained in post and were able to feed even when numerous fishermen were standing along the bank. In very wild places, you dont find such behaviors.

In the best US rivers, trouts are getting used to anglers, but they remain selective on the food. It was therefore possible to test different patterns of painted lead nymphs using sight nymphing to see the reaction of these fish. Starting to fish with Bullet Flies in sizes 12 to 16, we had a lot of refusals in places where the water is very clear with a depth when sight nymphing can be practised.

Trouts came to see this pattern of painted lead nymphs that they never saw in the US before, but refused because of a too large size of the pattern.

We then decided to analyze the size of flies with which the local fishermen fished in the most difficult conditions. He then revealed that the nymphs of size 18 to 24 were the most used by fishermen looking for highly educated fish, or during difficult conditions  ( low waters ).

So we applied the advice of the local fishermen, and indeed, we obtained our best results fishing with Bullet Flies in size on hook n ° 20. We wanted the Bullet Flies range to be adapted to the most fished river in the US, and that's why our collection is sold on hook # 20.
