took this flick a while back to compare the angles of the two. eventhough they appear very different - its suprisingly easy to hop from one to the other. both are soo much fun. i couldnt imagine dirt jumpin on a 20, but i guess i've never tried. but the pegs on the 20 are priceless. give me a ledge and as long as its only a foot tall, i'll ruin it very very loudly with a sickest 1 second long 2 peg slam grind to feet of pedals you've ever seen. thats right.
