I have a Shimano 6'8" M/XF spinning rod and 2500 series spinning reel I want to set up as a visitor "guest" rod for fishing smaller T-Rig worms (5" to 7.5" finesse worms and ribbon tails) and either T-Rig or Shaky Head (1/8th ~ 3/16th oz. weights) ... Pretty standard stuff - but needs to be forgiving to use and strong enough for people with inexperience . I was thinking either Power Pro #10 lb. ~ #15 lb. main line + several feet of FC or Co-Poly #8 lb. leader OR just a straight Co-Poly main line . Main objective is an easy to use spinning outfit for smaller T-Rig and Shaky Head worms that gets the job done - what is your line set up choice for this purpose considering a range of angler's ability  using this set up ?

My loaner combo is almost identical to yours and I have 30lb high-viz braid on it and add whatever leader is appropriate.  The heavy line was not intentional, it was just the lightest braid I had on hand, but I have grown to like it.  It's very easy to see, still handles and casts well, and if the beginner decides to ignore me and grab the line with their hand and pull, they get cut less badly then with thinner braid.  When I have to put a crank/treble hooked lure into a beginners hands I omit the leader so that I can be more assured of getting my lure back as most trebels will bend before the line fails.  

I would do just what u plan on doing.  15 lb power pro or similar braid to an 8 or 10 lb fluoro leader.  Works for me and anyone I let use my gear with those applications 

Thanks for the replies , I have 10LB. , 15lb. & 20lb. braid (PP) available and will opt for probably the 20lb. braid as being user friendly and creating less wind knots . I only have one spinning set up left that isn't braid main line  (drop shot - 6lb. FC) while all the rest have braid + leader. Now if I can just train new users to close the bail by hand and pull the line taught after closing the bail I'll be set.

 

P.S. I keep telling myself I'll try some of the newer co-poly , mono , FC lines that have come out for spinning reels as a main line  in 6lb. ~ 10lb. test but haven't pulled the trigger yet ... Based on a how to video  from an Elite pro - I have a shaky head set up with 30 feet of FC leader tied to braid with an Alberto knot that is the best of both worlds : Lots of leader length acts like FC line in the water without all the line twist / slinky effect because of the braid main line plus not having a reel full of FC line to contend with . FC + Braid knot goes through the guides and spinning reel bail while winding or casting with no issues either . 

If you use COPOLYMER or Flouro main line you should use a 3000 reel at least. A bigger spool makes these lines behave better.
