Line Follower - CONFUSED with some things NEED HELP

Projects General Guidance
1

Hey guys, I'm making a high performance two wheeled line follower. Basically, I want it be fast and accurate.
I'm planning on using 6v 10:1 gear ratio dc motor for each of the wheel from pololu.

I would really appreciate if someone would help me with the following issues,

  1. Should I use a ready made motor driver (Like L298n ) or should I make a motor driver using L293 chip and use ?

  2. Now, line sensors - again, would it be better if I make it myself using CNY70 sensor or I use QTR-8A Reflectance Sensor Array from pololu ?

  3. And which one will give better performance QTR-8RC Reflectance Sensor Array or QTR-8A Reflectance Sensor Array ?

THANK YOU in advance.

Yes you should use a ready made driver, but no not like an L298 or an L293. You're already buying from Pololu so look at their list of motor drivers

PS that doesn't make sense: both the L298 and L293 are just chips. In that sense they are both "ready made", as distinct for example from making an h-bridge with your own transistors.
