Welcome to the forum!!
Personally on all my trout rods i run 6lb P-Line. I am sure 4 would be fine.. I just stray away from 4lb line typically because I have lost to many lures in open water using 4lb. However Ice fishing I don't ever get snagged(Fingers crossed
As for baits.. Like said.. Try Ratso's, Rat Finkies, small tube jigs, small marabou jig's, small Kastmasters.
I have never fished Wolford or 11 Mile.. But Antero i have fished a number of times already this season!!
For Antero I would suggest using small jigs like mentioned in color white.(I have had the best luck on white.. Not to say that you couldn't do better using another color.. i just have had the best luck using white)
Tip your jigs with either a wax worm or meal worm(Waxies seem to work better for me at Antero) You can pick up waxies and mealies at Gander or bass pro... or typically at your local pet store
The bite at Antero is SUPER lite!! A marcum/vexilar helps allot.. or if you don't have one you can typically just look down the hole
Pretty fun to do to.. i still do some site fishing even when i have my marcum.
