I've been using the new Berkley Nanofil for a few months now and it's really nice. It's smooth as silk, no memory at all, very sensitive and casts a country mile. Only downsides are that it's sometimes hard to tie knots with considering I'm using 4# test and that knots slip easily. I use the double palomar but tying it to backing was downright painful. Good call with starting with braid on a spinning outfit, using it on a baitcaster is really different, or so I've heard.
i use 8lb nano fil on my wacky worm setup and love it cause i can cast a 4" weightless senko style worm a mile and a half and even though its white the fish dont seem to mind cause ive cought 95% of my bass on this setup so far this year. berkley suggest you tie a "nano knot" which is just a palomar that is wrapped threw itself twice and it holds great ive never had an issue with that knot, yes it was a painful nightmare tying it to the backing they suggest an albright but i couldnt get it to hold so i just tied it to the backing with a triple surgeons knot . and it gets frayed pretty easily so i usually end up re tying after every third or fourth fish. as for braid its all about power pro super slick! i use 50lb on my frog rod as well as my flippin stick, i use 30lb on my carp rod and 15lb on my topwater spinning rod and i pretty much use a palomar exclusively with braid cause ive never had any problems with it slipping or coming undone and it can be tied in the dark. when using braid though keep in mind you will generally want to have rods with a softer tip to make up for lack of line strecth , it will act as your shock absorber otherwise you may find yourself ripping hooks out of fishes faces alot
