I got a sweet deal on a Redline XXX and used the excuse that I would ride and jump it during the winter for cross training and go back to my Stinky in the spring. Now that my wife is fooled, I wanted to see if that would work. I know that a lot of sweet riders came up from BMX, but it's been 10 years since I rode a 20". Could it be worth it to dirt jump on the 20" to tighten my skills and go back to the more forgiving 26" in the spring? Also, if I dig dirt jumping like I know I am going to), it will give me a reason to build a sweet Planet X in the Fall
