This can only be determined by you, all the info above is good and correct but it gets down to where you will spend the majority of your time fishing and the techniques you plan to employ on these waters, otherwise using the proper tool for the job. If you rarely get on the Bow than a 7 is overkill unless you are target Bulls on the mountain streams whereas if you plan to fish in high water and bankpound streamers then its the right tool for the job. If you get the right 7wt you can even use it for bones in the tropics wind permiting. Hope this helps Tight lines!
