We've had great luck & good prices with Hogin Sales in Alameda CA (they will ship). Our top ODCA Ariel class boats used this loft. If you contact them, ask if the Ariel Class discount is still available.

Here in SF Bay we use a 110 during the summer and a 120 or 150 for the lighter winter breezes. Check this thread on track placement as it's different for each sail:
