I use my John Wilson avon 1.25lb test curve, superb as I've mentioned before, covers so many techniques in one rod. I've never suffered a hook pull using this and agree that pulls are going to be down to the stiffer action on your chosen rod.
Last Tench session I used Maxima 10lb mainline (A bit hefty I know but the venue contains carp to 20lb at least) with about 8 - 10ft of berkley vanish 6lb flourocarbon holding the float direct through to the size 14 Drennan super specialist barbless hook. Worked a treat, the berkley vanish is incredibly thin for the strength and very supple for flouro with little memory either, superb for hook lengths and float fishing with stepped up tackle.
