Alpine usually has a 65' table at the prime of spring. Last year (or the year before), there was a really sick JOI style gap with a wide takeoff and a steep lip as the last jump of the line.
Usually Kangaroo has a 4 jump line, a seperate booter on Nick's run with NOTHING in the way of the inrun, and a rail line next to the jump line. The jump line is really quite big(1st jump is usually 25feet, and they get progressively bigger), and the booter is huge (seen Kangs, dub corks, dub flips, etc. tossed on it in years past). For a smaller line, look to Kangaroo Ridge, which usually has some cool jibs (tire, giant rope bobbin, oil drum, spine with a big fat log on it, etc) and a poppy line of small 15-20 foot jumps.
