I am more partial to colorado blades than indiana for casting. Some of my BB rigs have a big Indiana for diff times of year. I like #4 colorado gold, deep cup and plain. BB rigs are 2 hook Mustad. Avoid baitholder hooks (with shank barbs) on BB rigs as the barbs will cut the line. Short or long shank are used but size is your choice. One picture shows a size relation for caster hooks etc. 3 and 4 mm beads and it shows the blade covering the hook eye for cast rigs. Single hook, use half worm and try to push the worm head over the hooks eye and keep bait straight on the hook. My cast rigs are 18 inch and BB rigs are 3 to 4 feet. The other type blade spins very easy in a light drift and available in a few diff sizes. They look like a propeller. As far as blades after the mayflies hatch I change colors more and try to fish in areas less prone to the concentrations of bugs like rocks or way out in the flats near Canadian line until mid July. Always have multi colors of blades and diff weights in your pocket to change out till you find the right combo. I have caster weights of 1/2 , 5/8 , 3/4 and 1 oz should be good for any western basin day. BB weights I use 3/4 oz up to 6oz with 2 ,3 and 4 oz used most days. I tie my rigs with 17 pound Vanish line.
