i agree, about 3 months. every solid video i've put out (winter mini, autumn mini, TD part) took about 3 months to film. a lot of times you'll film a trick and then a month later it'll be obsolete.
yea, i'm pretty sure the current pro costs like less than 20 to make, this one shouldn't cost too much actually. but if the deck ends up being good nobody will mind paying a bit extra anyway.
