Yup great points, marinb. Such a diplomat.
I'll agree it's really down to personal preference. No need to argue about it.
Have you guys done any custom tuning to your bikes? I'm running a tune that was created for a bike virtually identical to mine. Same mods and everything. The dude sent me the file and I used a tuning software to load it into my ECU. Talk about geeky. But damn was it worth it. And he wouldn't even let me paypal him money. He refused. This is easily worth a thousand dollars for the engine performance on my bike compared to stock. Just like those who have the tunes on their Z4M's. They rave about it.
