I have a couple of older orvis monic lines for colder water ( the blue ones) which are braided mono core intermediates and they shoot like crazy as long as you haul and don't take more than two or three false casts at most. They have a relatively slow sink rat 2"/ sec I think, but I have had great success with them for distance. They need a good stretching at the beginning of the day and use a basket. As for sinking lines, RIO Deep Sea is it IMHO I have a 250, 350, 450 for 8,9,10 respectively and all cast great.
