Nice. I have never upsized for plastic lines, have heard of some who do.
I have a few silk lines, they cast great because of the smaller diameter but need to be dried out after a good morning of fishing.
Also have some Cortland "Sylk" lines, they are fine for closer in fishing but lack the back bone for longer casts.
I'll be checking the NFCDL in a week or so, trying for some winter fish before the melt starts.
