Re: Need a good powerful rod...
Welcome to the forum. I saw you post earlier today but wanted to think about it for a while.
BlueDun has give some very good advise. The most powerful rods available are usually saltwater rods. The Xi2 should be a very good choice. The best choice may be the Sage TCR but it is a very fast/stiff rod and you need to be a good caster to handle one. It sounds like you may be at that level.
The new Scott S4 would be a good choice. It is new for 2008. If you could find last years S3 you might get a good price. You should also look at the Loomus Cross Currant in a 9' GLX.
All of these rods are top end. Salt water rods usually have heavier butts to increase lifting power. You may not need this feature. If there is any to cast them it would be a big advantage.
My comments are directed at your choice for an 8wt.
