JerseyBrian said "Cheat and bring some chum and dead bait" - theres a sign of a newbie.
Good jigging will outfish bait JB - just stick with it and you will see the light.
On your question of lightweight jigs - I've caught fish to over 70lb on jigs below 100gms, and always use the lightest jig I can.
For Snapper try a 60gm River2Sea Sea Rock, bomb it straight down wherever you mark fish, try and get at them with a direct hit, don't worry because they will intercept the jig before it can reach the bottom!
Just watch the line entering the water and as soon as it stops, engage, wind fast and hang on.
SeaRocks are tail weighted jigs, if you cant get some where you are, use any tail weighted jig that is shortish in length BUT I have a friend who gets his snapper on a long tail weighted jigs, so what the hell!
Yea, I'm definitely a newbie at this whole jigging thing

but who says bait fishing isn't fun! Especially if I can get some livebait with my cast net. Feeding small fish to big fish is cool

... like when you start to feel him on your line trying to flee....hehe Don't matter if it's live bait, dead bait, finesse, jigging or popping...I LOVE FISHING and I love every kind of fishing there is. I hope to learn as many types of fishing techniques and styles as I can in my life. I love expanging my fishing repertoire, and mostly my fishing knowledge

I started off as a kid using line twisted onto a ruler off the Oradell Ave. Bridge which was 40 ft off the water so you can tell I was obsessed as soon as I caught that first Sunfish...and I'm down to fish; with whatever.
Thank you for sharing your experiences on jigging lighter lures with me though! It sssures me that I should get a real assortment of jigs that range from light to heavy, from short to long...always prepared for what conditions await me..

I'm stopping by a few stores this weekend so I will look for what you suggested. Thanks again!
Pescador ... that newbie comment wasn't neccisary at all. First off not everyone loves jigging 100% I bait fish as well. Why do you need to be a newbie to use bait?? Doesnt make sense.
I've always been fascinated by speed jigging and with my tax return money, now is my chance to get my own jigging setup and start learning!!! Gotta start somewhere. I'm an experienced inshore popper though. Can't wait to start throwing those 4-5 oz poppers to tuna, roosters, cubera, etc... I know already its going to be a totally different action/movement. I love it.
To answer your question Brian, depth has something to do with it but if the current is ripping regardless of depth you will need to increase the weight. Its the same concept with bottom fishing, i could be in 50 feet but a 2 ounce sinker may not work
hmm, very true. Strength of current and tide >> depth. Thanks Glenn
Sorry I ask all these 7 part questions guys

But I'm trying to learn as much as possible and you guys have been great. Very open and helpful down to a fault. Fishermen 4 Life!
