I always used tweens but now I've moved onto drawn fbf, i might start tweening again using masking for 3D animations.

A combination option? I pick and choose the best suitable method for what I want to achieve.

when I use flash i'll probably use a tween yes because that is one the advantages of flash

tween is win

The last real animation I created was paper FBF (It isn't on Newgrounds) But most of my movies are tweened. There isn't anything wrong with tweens, guys.

Usually FBF, but then I'd tween it across...

Two thirds of what I've submitted to Newgrounds was painstakingly animated frame by frame. Except for the couple of seconds in Magic-Shed with the side view of the bicycle. And even then, I didn't tween or use movieclips.
