Hi there Woosh, I have been at this for a year and I am just starting to get the hang of it. I can think of some guidelnes that might help.
a) On lakes like Lafarge, you want to go within a week or two after it's been stocked - keep an eye on the stocking database on this website.
b) I have almost invariably found early morning or dusk produce significantly better results.
c) If they are biting and your hooks are sharp you won't have to worry about what the bite feels like - when I was at lafarge two weeks ago they were hitting the fly so hard I did even need to worry about making the strike (one actually broke my leader) . At another time I simply found they were on without me even feeling the bite. (If they are biting hard, trust me, you will know!)
d) As for the speed of your strip - try different things. Last time I was at Lafarge they seemed to prefer a faster strip rate but I don't think there is any rule
e) Also, try different depths - use a coundown before you start to strip (say 3 seconds first cast, 6 seconds second cast etc. I have been using a floating line with about six feet of leader)
All I can say is keep at it. Last year my success was limited, this year it's getting better and I think it's got a lot to do with timing. I am really finding it helpful at my early stage to head out for stocked lakes pcking the morning or the evening as my time. (Not sure how long a lake remains good after a stocking - probably fished out after about two weeks).
As for casting, I took a class and I am still crap at it but I think I would have been even worse without the classes
