well the fly lets u keep ur screen but if u dont care about the screen then go with the pred 2. it comes with eyes and the board is uncapped so its a bit faster and it adjusts everything itself and can link to a computer. and it costs 50 less. but if u want the screen go for the fly.
you dont miss the screen to tell you the truth, when you turn the gun on its instant on and eyes are one to turn off eyes you hold the trigger while the gun is on for 5 secs then eyes are off. to change anything in programing just hold the trigger then turn on and program very easy... as far as eyes they work perfect i played with it this weekend and no chops not one,
how fast is it to be honest that is what i am looking for because right now something wrong with my board on my 2K2 DARK LCD it wont change modes of fire and nobody none of my friends can even shoot past 14BPS with the mrof set at 20
