First off, I would like to announce that I live in Nebraska, so saltwater fishing is a rarity.  In a month, I will be in Costa Rica.  I am going to do kayaking on Lake Arenal and will also be stopping at the occasional beach, predictably on the Pacific side.  I would like to fish in both of these situations for whatever bites.  My current setup would be a 2500 Shimano Nasci with 15 pound braid (and leader) on a 7 foot MH fast action 3 piece rod.  Will this be enough to tackle the bigger fish found at their beaches?  Should I get a larger reel/heavier line?  If so, any offers or recommendations?  I don't think we will be spending days at the beach, guessing around 6 hours total.

I found Shimano Nasci's for $90 in the 4000 or 5000 size.  Should I go with those?

I'd go with the 4000 with 15 lb braid

Do you think that would work for rainbow bass also?  They're essentially peacocks with different coloration and teeth.

No idea what they are, how big they get or their habitat so hard to say.  With that said, I tend to think that selecting the right leader to add to your braid gives lots of versatility.

There is a lot of trees along and in the shoreline where they live.  I have read that they run straight into these roots when hooked.

I think that I am just going to stick with the 2500 and the 7' and save my money for a new baitcaster or ultralight.
