Cork and Bait Question

[Gasper Master]

What kind of corks do you prefer? Popping corks, Egg shaped corks, with or without the wire with weights and beads attached?

Also, what do you like fishing under a cork and how deep? New to speck fishing and all I have ever fished were DOA's under a cork.

Reason I ask about the cork is b/c we caught a few trout this weekend and my buddy had way more fish hit his rig than mine. I was fishing with an egg shaped cork with the wire, beads, and weights. he was fishing with a popping cork with the wire, beads, and weights...
