Sep 4, 2001 3:57 AM | | Obviously the Bommer is steel but other than price what's the differences between the Classic and the RAD? Do all three have similar angles? Couldn't find out too much on the PX website. |

Sep 4, 2001 4:04 AM | | Jack Flash classic is made out of 7000series aluminum, while the JF Rad is made out of easton's secret rad aluminum (a bit lighter, stronger by a bit, a ton more expensive) and the bommer has steeper angles and is only available in 21.75in tt. I'm getting a bommer soon. The JFC is nice, and unless you're ultra weight concerned, the JFC is sweet. |

Bommer = shorter and steeper.ideal for throwing about on dirt jumps.
Jack Flash = slower, more stable, longer. better for high speed stability. |
