OP, definitely wait for new boots unless you are absolutely sure that you aren't getting new ones or if they have the same BSL as your old ones, and as others have said, there is not much adjustment at all. As for the din setting, if you don't ski above an 11 and you aren't going to max out your din anytime soon, definitely buy the 12's, as they are less expensive and just as durable as the 140's. The only reason I would go with 14's is if you ski above an 11 din and might go past that eventually, but both bindings are rock solid. You won't have to worry about smashing them to bits because the heelpiece is all metal and the toepiece is almost all metal also. I recently bought a pair of FKS 120s over the Pivot 12's only because the heelpiece has a different layering over it instead of paint, which gets really scraped up after a while. Plus they were only like $5 more anyway with no tax and free shipping. Hope this helped
