Yeah, that's the Islands.
For those small ponds/lakes, you don't need all that crazy tackle.
Inline bolt rig is good to use in deeper water and you can get it out further. But you can make a simple bolt rig with a bell sinker, a couple of swivels and a bead.
You really don't need all those lead clip and slider (with some odd exceptions). You can do-it-yourself a lot of the times.
Stealth sinkers -You want a sinker that look more natural...like a pebble or a rock...so get some sand, coat your bell sinker or egg sinker with a bit of epoxy or super glue, and roll the sinker in the sand. Voila...stealth sinkers.
Lead clip - You want a bolt rig system where you can switch up sinkers of different weights...use a small snap swivel. Or you can adapt one of those safety pin type spinner and use the safety pin mechanism.
Running rig - That's just a simple carolina rig...really...
Flat side sinkers - I'm stealing this from Eli
You want a flat sided sinker for bolt rig? Just take a bell sinker, grab a hammer...and hammer the sides flat! You want a flat sinker for running rig? Again, grab an egg sinker, a nail that fits into the hollow tube inside the sinker, oil up the nail and insert it into the tube of the sinker, then hammer the egg sinker flat. Remove the nail when done (the nail is used to keep that hollow tube in the lead. Otherwise, when you hammer the lead flat, you'll hammer shut that hollow!) Simple!
Try to understand the mechanics of the hair rig. All it boils down to is the way the hook is positioned in the carp's mouth and how the hook point sticks into the lip when the carp blow the bait back. At that point, the carp gets scared and run. You don't need those fancy weights a lot of the times. A bell sinking on a running bait rig can do just the same. Even an egg sinker will suffice on a modified carolina rig.
What I would suggest is just to spend time on the water experimenting. Read about all these rigging and then try to do-it-yourself by adapting the concept of the rigs with your existing tackle (any types of hooks and sinkers you have)...and then fish them. Once you experimented and get some results, you'll then understand why and if you do need the fancy tackle.
I'm not saying the fancy tackle isn't needed at all. There are times I'm fishing wishing I have some fancy tackle...but then the majority of the times I do just as well with bell sinkers, egg sinkers, and simple floats.
