To begin with I'll probably be fishing on a bit of canal that I've had plenty of nice perch from. Theres a section of it that runs through open fields so plenty of space to cast

not too wide and 4ft deep at the most usually.
I'll give the Ti traces a go but if it does have an adverse affect I'll change. I'm sure a split ring would sort things out though, probably wouldn't put them off either, I've watched the little buggers take the swivel at the other end of a trace before
I know what you mean about the weight. I've tied marabou jigs for use on the UL gear and used a jig head hook to tie them to, it does make them bob up and down nicely.
I'm not sure but I think the hooks I used are 2/0s, will invest in some more anyway lol
