I'm also a believer in keeping things simple when possible. Sometimes though when setting a 'trap' you have to be rest assured that if it gets tampered with , it's still fishing for you. Through most of my carp angling, I've angled on silted up meres (27 yrs) and for a fair bit of that time I used rigs fishing in the silt, 'where the food is' . It's so easy for your hook to foul up and then your sitting there unbeknowing what condition the hooking arrangement is in. Many a time I've watched carp bubbling over my bait and not had a bleep, I've wound in, recast to the same spot and had a take within the same feeding spell. I prefer bottom baits than pop ups when fishing in silt and if I'm fishing in daylight where I can watch for activity, I will happily use them. When I use them at night and I get unexplained bleeps, I tend to give it 30 min, then I feel like I need to wind in and re cast and in most cases I will. That's where stiff rigs with pop ups are effective from a re-setting perspective, along with the other obvious advantages.
