Just got my 42 rear from skater69 on the org the other day and went for my first ride today. I already had the 16 front and I really like the 16/42 combo. I only rode about 40 miles today, but could definitely tell a difference. 2nd gear wheelies are effortless. No clutch, no on/off throttle to load the front, just nail it, and it's straight up. I love it.
