What is the best way to prepare gambli for long casting? I mean, so when you cast you dont end up seeing it fly another direction

I remember in Canada they used to get salmon eggs and put them in these small mesh transparent nets and tie them and when you cast everything stays in one place and they dont fall off as easy, even after a strike. Obviously you would have to prepare them the night before.
Would this be a good idea?
