Yeah, that's what I meant. Guess I wasn't clear enough. A BD bike is probably his best option no matter when he decides to get it, I'm just saying he should wait until he knows whether cycling is something he'll really be into rather than throwing $300 after a fad he won't care about in 6 months. It sounds like he's got a fine road bike he can be riding right now.
Even though I agree with you sometimes fads aren't such a bad thing. I first started skateboarding when I was 12, and at that point in time the skateboarding fad was in full swing. But I still got 5 years of riding out of it, and it was super fun while it lasted.
Like I said though I do agree with you because
1. Biking is more expensive.
2. Much more complex sport in terms of what you could choose to do with it. (Still would rather buy a BMX bike for tricks...)
