Many people build their own so they can respond to changing conditions.
I would suggest smaller blades (1/2″, 3/4″) for good lite and early season and larger blades for later.
I keep a selection of silver, gold, chartreuse, fleck in gold and silver. Effective color combos are going to change with conditions, similar to stick bait options…
Usually I spin Indianas, but colorados and willows do well also.
I always tie a stinger hook on also, at least for crawlers and leeches. catch 75% on that hook. I usually down size that hook and put it 2-3″ back. Helps slow down bait theft.
Bead color is not to be ignored also. I keep two sizes, medium and small.
I usually order from Cabelas or Ebay.
