Thanks for the replies guys! I think I'll love the rig once I get it! I might go ahead and get the 8wt after all the recommendations.
The reason I was going for 7wt was because I plan on giving my 6wt to my sister. (She finally caught another fish and she's hooked again!) She used to fly fish for panfish with me, and she hasn't been out for a few years. She got her first taste of muddy water action too by catching a gar!
Also, I plan on getting a 9wt down the road for some smaller pike/salmon.
