I think you try and manage both. Get them both started and establish the relationship. Given the closer one is a 2 year project you have time to figure out how to work this. Figure out from each guy what kind of timing and response will be acceptable for them and work off of that. Most people dont want to be dealing with multiple "strangers", so if you can establish the relationship and manage expectations to their satisfaction you are golden. Finding a wood burning partner who has room for storage is a great idea....you may not know one now but I find more and more wood burners as time goes by (sort of like when you buy a car, you see them on the road all over).
