TomRC -

I do some trout fishing with a medium fast action Sage Fli 9' for 7 wt, for bigger water, bigger wind, bigger flies, and bigger fishies. I went to the 7 wt for conditions that really stressed my 5 wt ( and me ) but can fish small dries and nymphs as well as large nymphs and nymph tandems and streamers with it.

If the 6 wt you have in mind is also right for the bass fishing you want to do, go with the 6. If you would prefer a bigger rod than a 6 for the bass, consider a 7 wt - a 7 won't be a liability when chasing trout.
