Go with and swingarm at less 64-68 over.
Some tracks reqiure that you have a swingarm or the extensions be welded on.

I've had extensions at 66" for over 5years with no problems.
If you have the money I would get a arm.
As far as the gearing, I think your going the wrong way. Having a longer wheelbase you can go the other way with gearing.
For example, I'm about 8" over (66") and I run 16/48, but I'm 200lbs in boxers... The lighter guys can go with less gearing. To me, more gearing is easier to keep it consistant.

I was debating getting some extensions for my stock length boosted 14.......just wasn't sure if I could trust them with my life. Who makes the best ones?
