Virtue Internals are the way to go, seen far too many problems arise from Lucky internals.
Plus with Virtue, you get a life time guarantee and software upgrades.
True it costs a bit more, but that extra cash is well spent.
Lucky parts also come with a guarantee and because they have a european branch, you dont have to mess about sending stuff to the US like you would if you had a problem with the virtue board.
Plus you can speak to someone on the phone if you need advice.
Also the Lucky board comes with a new solenoid which is a massive upgrade over stock.
In comparison to virtue, the lucky board has better eye logic and the more powerful chip it uses means its more responsive to the trigger.
