FireWire is on a distinguished road

There has been a lot of threads on this.
Some swear that 89 is better and some say no difference from 87.
I am a bit cheap and have only ran 87 since I got my truck.
Now gas prices have gone down and 89 is the price 87 was last week.
I guess I'll finally try a tank of 89 and decide for myself.
