My 33 year old wife is facing a decision on Copaxone and I'd be interested in people's feedback.

Bit of background - she had her first Optic Neuritis 11 years ago and subsequently has had one more Optic Neuritis 4 years ago and a Sensory relapse this year - so 3 relapses in 11 years. In all cases she has recovered 99%.
After the last attack our Neuro reviewed her case with the New Zealand expert on MS and he has recommended she go onto Copaxone. This is a big decision in New Zealand as no CRABS are subsidised unless you are EDSS 4 or greater so it is a significant cost.
Thankfully we can afford this but I am slightly torn as to whether it is really going to be woth it.
Cons: I have read both the Cochrane review of Copaxone and a recent review in the European Neurology Journal http://tinyurl.com/4cx3ye which indicate Copaxone is no better than a placebo at preventing disease progression.
Pros: I understand the side effects are very mild and I have read the long term study showing substantial reduction in disease progression on those who have stayed on the drug for over 20 years (of course, the study has incredible suvivorship bias which may make it worthless?).
Are we really going to be achieveing anything paying to go on Copaxone? Should we be asking to look at TYSABRI which appears to be the most effective? Or do we cross our fingers for the next two years until FTY720 or Tovaxin hits the market?
I realise these are not black and white questions but thoughts would be welcome!
