A lot of what I have read lately says the blade from the chatter creates some funky water currents and the hammer/boot tail can't function like it's meant to. Basically other trailers like curly tail grubs, senko type, craw type and the fork tail blade something by strike king are better trailers when used on a bladed jig.
I'm pretty happy with my swim jigs being bladeless. I haven't delved into to the whole bladed jig thing yet...
