I advised in a earlier post working on 40' casts. Note I said with one or no false casts. If you are staked out, those fish can be on you in a hurry and you have to be able to get that fly in the water fast with accuracy. 80' casts are fun but aren't always the money casts.
I own a 5 wt NRX. The wraps are truly unfortunate but it's a wonderful casting and fish fighting tool. I've been told that it's even better in the higher line weights.
