Re: "Crack" noise on either forward or backcast
Mr. Rispin is absolutely right about the sonic boom. We can't expect that 5x that we play gingerly with our wispy 4wts to survive such violence either.
Its also possible that wind is playing a part in the creation of this cracking noise. If the wind is behind you and you are trying to throw a long but underpowered and mis-timed backcast into the wind, its very possible that it won't straighten out before you begin the forward cast. This situation is especially likely in coastal conditions or with Rocky Mountain winds and light rods. I find that it helps to keep the false casts shorter, and to haul hard and shoot high on the delivery of the cast to achieve the distance needed. This will be easier on your arm and shoulder too.
