Your rigs aren't balanced enough which, in general, means what a lot of people have said here is true. weight and balance is all off. mono is soft and flexible, with a light bait and a long hook link over say gravel or other hard lake beds means that when your rig has curled up over the bottom the carp is sucking in the hook and moving at least 1-2ft before you even get an indication. At this stage the carp is already nailed and any over eager 'strike' is simply putting that hook in solid. Have you ever been 'bitten off' by a carp? If so, read about Chris Yates and his exploits with the kidney bean bait...
If you want to use mono, shorten 'em up, foam the hook and drag it all back towards you 5 seconds after the lead has hit the bottom. Consider a heavier guage dead sharp hook like Kordas wide gape if the water is not too crystal. Whatever you do, make sure you learn from it by changing little bits at a time and you're more than halfway past cracking the mechanics! keep the klinik nearby and don't panic when they're on the bank
tight lines! Safe angling!
