You might want to investigate the Airflo sink tips preoduced in England but available from many American suppliers.
These come in various weights light trout ,trout,and salmon.The salmon tips are on 25lb mono.
They also come in about 7 different sink rates from floating to 13"per sec sink
They are available in two lengths 5' and 10' They have built in loops of braid for loop to loop connection.
I would suggest that the trout weight in 10 ft tips would be appropriate for a 5 or 6 wt line. The tips turn over very easily when fished directly from a dt or wf floating line.
