Ahh Ash. Now your talking. Welcome to the next stage of kayakfishing. The mirage drive will catch you more fish than any other piece of fishing gear you own.
I would say definately spring for the turbos. I would also grab a sailing rudder while you are at it. Those upgrades make the best fishing kayak much better. It was the best decision I made to upgrade. The boat is much more responsive with the sailing rudder and the turbos provide the needed resistance for comfortable peddling. With the standard I always felt like I was peddling a bike downhill. Very little resistance. Also with the turbos you can practically pull a hole shot when getting up to go and chase breaking fish or moving out of a dangerous situation.
