I don't know how you throw the ball, but that seems like a pretty good spread. Might not need the 3.5 or Siege, since from everything I'm hearing, you don't need anything super aggressive...Just controllable down lane. The lanes are hooking more than last year and I primarily used an Evil Seige on the fresh last year. I would think your Anaconda might be enough ball for the fresh with the pin down position.
The 2.5 and the Urethane should be good for the singles and doubles burn.
We head there in two weeks and I think I'm going to leave my Alpha behind and stick to my Wicked on the fresh. I'm taking 5 balls and I'm thinking of adding a pin down Loaded to my arsenal when I get there.
