Can you catch bass, bream, crappie and bowfins on a spin cast setup?  Yes, you can.  Here is proof, watch this video:  https://www.youtube.com/watch?v=lLP9LaG20mM.   Using a Pultz Camo Frog with a regular hook Justin catches a variety of fish using a spin cast?  The Pultz Camo Frog is available in hook sizes 4, 2, 1/0, and 2/0 from BreamBugs.com.  When using a spin cast add additional weight to the popper to make it easier to cast, thread about ¼ inch piece of Stick Worm, large size, on the hook.  When casting with a fly rod the added weight is not needed.  For large poppers it is best to use a 7 or 8 wt rod.  See all the Pultz Poppers at www.BreamBugs.com.
