Save yer money and get the original Showas re-valved and resprung by a decent expert as then they're just as effective.
If it's the bling factor you're after then Griff at AP can have them re-anodised to look like Ohlins. This aves having to get the Ohlins compatible yokes too ;-)
If I had some spare dosh I'be contacting PaulW 'cos he's got a pair of the 05 radial mount Showas for sale complete with brembo radial calipers and master cylinder for the best of both worlds.
Calipers & m/cylinder sold, forks still available. As Jon says I'd rate them as good as Ohlins when set up, won't need to change the yokes and they don't blow seals every 5 minutes!
