I have the Midge. It's a great 3wt but not much of a 4wt.
I also have a T&T 3wt 7 1/2' and it's my go to rod
The Midge is a great rod for the price. Having the etra tip is also nice even if it is a 4wt.
You could also over line a 3wt real with 4wt line.
Just go test em out!!!!!! and don't listen to Uber
