I use brass n glass that I purchase at Star Mart near Lake Fork. If they are out I use lead slip sinkers. I mostly use 3/4oz weights. I have tried 1oz weights and really don't see any advantage to them over the 3/4. The 3/4 gets hung up less, at least for me it does.
They're expensive but I've been using the Picasso tungsten flipping weights in plain color. I use braid as main line and they won't eat away at it. It took a little getting use to the feel of them and braid because you feel like you're getting bit but you get a very clear picture of what's on the bottom and I love it now. You can use a bead and or brass clacker not only for noise but as a knot protector but these weights work fine without them.
I used tungsten bullet 3/4oz for a long time but I fish fluorocarbon main line and they just knick it up too bad. Went back to 3/4oz lead egg sinkers and really other than losing a little sensitivity when going over bottom structure doesn't make any difference and is a lot cheaper.
