Two Handed Overhead Fly Rod

#1
I’ve been fly fishing in saltwater (stripers, Blues, sea trout, etc.), for well over 45 years with single handle rods from 7 to 10 weight. Presently, I decided to try 2 handed overhead rods to achieve more distance only when needed. I just bought the new 11 foot, 8 weight, Deer Creek TFO 2 handed rod. (Mfg Recommendations - 400-600 gr. or 7-10 weight lines)
Three Questions-
a) Suggest a manufacturer’s line for maximum casting distance in 3’ deep flats, (light winds), an Intermediate line.
b) Suggest another manufacturer’s line for fly fishing from a jetty into 25’ of water depth, (light winds), a medium sinking line.
c) Finally, suggest a line for fishing the heavy surf, (moderate winds), probably medium sink line.
I assume that fly lines would either be heads with looped running lines, integrated line heads, or Weight Forward lines.
A tough question, but would really appreciate recommendations from experienced 2 handed overhead anglers. Much thanks!
