My 2 weight is 7'9" and I like that allot. I had a 3 weight the same length, but gave it to the hubby as I prefer the 2. Then I go to the 4 weights, which I have several 7' and one 8'6". I bought a 7' 6" 4/5 blank I will be putting together this fall.
I think 4 is my favorite, but I have the Orvis 1 ounce full flex, the Trout Bum 4 weight full flex, a Lamiglass, and 2 bamboo...so being full flex makes those 2" fish just as fun as my faster action 2 weight.
I used the Trout Bum on some trophy size Bluegill once.....the tip ALMOST touched the handle...what a blast.
