The float and fly method is best for water temps below 50 degrees and is best suited for highland reservoirs and requires a minumum of 8 foot of visibility. A weighted 1 inch fixed float is a must because the best size of flys are 1\16 and 1\32 and in cold air your line doesn't slide thru slip bobbers well and you don't get the good shaking motion that is needed on calm water days. I have boated 50 smallies over 5LB's at least every winter with this method and it is great on cloudy days but if the sun is shining it is not good. A 8 foot rod is perfect and you can't get by with shorter but you don't need longer, normal float setting is 8-10 foot above the fly. Jim Duckworth
