I'm looking at the duo realis vibration and the tetra works bivi. I'll be using them to catch perch. Which of these two should I get. The websites below are them. Please give me your opinion.

My opinion is not to overthink it. Never having used either of those lures, I'd say choose whichever you think you'd have more confidence in. Perch will take a wide variety of lures and anything appropriately sized should work. Make sure that the lure covers the depths you want to fish.

Like a well seasoned tackle junkie my recomendation is to get both. Like a well seasoned angler my recomendation is to get several from different companies, not a big bunch, just a couple of these and couple of those and so on. There are days everything works, there are days the want one but not another.

Wow that bait is tiny! Duo makes great baits and are well balanced (extremely critical with tiny baits like that) so I'd be leaning towards the Duo bait.
