Dolphin....7wt?

[fowlshot]

goin offshore tomorrow and i wanna try to catch a peanut or smaller dolphin on the fly. i have an Orvis TLS 7wt, Sage 1830 series 7-9wt reel.

i know its really light for the phins, but i had my dad hold the tippet, and i walked down the street(i live on the corner) and stopped at the end and i still wasnt out of backing. id guesstimate the road to be 200 yds. (btw, i just got the reel and when the guy put the backing on the reel, he didnt tell me how much he put on, and i forgot to ask.)

and fly wise, im thinkin either pink and white, or green and yellow. ill probably tie up some flies with EP fiber and bucktail?

should i? im not planning on going for any big dolphin, but im fishing in a school club tournament and i wanna win the last tournament!
