After searching the internet for further clarification I came up empty handed. I also emailed the guy who initially submitted this technique but no response. So I did my own research and after reading this ad I noticed certain key phrases that immediately caught my attention. I pretty much found the answers that I was seeking. This inspired the development phase of this adventure. The following are some products & an idea of achieving optimum results:
Drennan Crystal Avon Floats
The Crystal Avon is designed for fishing in rivers or canals that have a steady low flow. Its crystal main body blends into the water, reducing the chance of being detected by fish. If the river depth is only one or two feet, any other float will be noticed by the fish as the presentation is so close to the float. Its widened mid-body increases stability in turbulent waters, reducing the wobbling effect. The thinning of the float's tail increases its sensitivity by reducing the friction when being pulled by a fish.
For spinning anglers, the Crystal Avon can be used to drift in small streams for cutthroat trout, rainbow trout and dolly varden. Ideally, this float should be used in two to six feet of water that has a slow current. Your other gear should match the float, therefore light line such as 4 pound test and small weights should be used.
Its sensitivity allows the smallest bite to be detected, yet it does not submerge when following by eddies. Differentiation between a bite and a snag is very easy with the Crystal Avon, a feature that a foam float cannot deliver.
The Crystal Avon comes in four different sizes, ranging from 6" to 6 3/4". The largest size is ideal for the small streams, whereas the smaller ones cannot withstand the current of most streams.
In addition to the length, each float is marked with a gram weight on the side. The four gram weights we offer are 2.5, 3.5, 4.5 and 6.0. This weight is not the weight of the float itself, but rather the amount of weight in grams that the float will support. We carry four colors of caps for these floats, yellow, orange, flo. orange and flo. pink.
