6wt is the minimum for inshore species. I fish a Scott Heliply 6wt inshore when the wind is down, but it has very good backbone for a 6wt. You can fish the 6wt, but a big redfish will whip your butt. The most versitile weight for inshore is an 8wt and this is the weight I fish most of the time.

I would suggest you find a medium/fast to fast action 8wt. You are not going to get blazing runs with specks or redfish, but you may hook into a big jack or mackeral. I would make sure you have a good drag on the reel.
