If you are going to tie your leaders you can add a couple of sections of HI-VIS colored mono. By doing this you can create your own nymphing leaders. You can figure out the depth you are fishing by knowing where along you attached you HI-VIS. I have used them for maybe 5 or 6 years now and when I fish old school (no indicater) this leader really shines. If you send me your address I'll mail you one of my set ups. You can buy this mono line from Cabelas. I also use Trilene HI-VIS in green.
