there are huge advantages with MPFI, I run a MegaSquirt MS3 Pro on my slant. Fuel and ignition controls at your fingertips, it also has a two step delay, electric cooling fan controls, data logging and a lot of other toys built into it. The problem is all that costs dollars, then there is the installation time, the learning curve... personally I would not do a TB. But that is my choice.
What is the right carb for your build,, keep looking at threads and talk with folks that have done what you are wanting to do.
If I was 15 I would keep it simple and keep it cheap, you will have ample opportunities over your lifetime to spend money.
