Aero bars and indoor bike trainer

I have profile design areolite I have long arms the areolite have incredible adjustability.

Aerobars come in different lengths, and have various hand positions. The Profile carbon stryke bars are popular. I would not recommend S- bend bars as your first set of aerobars as they lay out your wrists in the most agressive position you'll often see pros using.

IMO it's a matter of personal preference - you should go down to your local LBS and feel a few different kinds that they have on their bikes. There are a ton of models/designs out there, and there isn't really one that's the "most" comfortable. I used to have Profile T2+ S-bends on my old bike, which I liked a lot and to me were very comfortable. My tri bike now has Vision Tech r-bend bars which I like okay, but they're not the greatest. Check a few out and go with what works for you.

As for trainers, I have a piece of crap CycleOps Wind that I got on eBay for like $40. It sounds like rush hour traffic in my apartment when I'm on it, but hey, it was $40. Expect to spend $150+ for a new one.
