Also once you switch equipment you're back to a "new hire," reserve schedule, just paid better. Assuming you move to new equipment at first opportunity and are at the bottom of the equipment list.
Now someone will post that they've been on LC since they were hired and how awesome it is.

LC is going to either a) suck, or b) go very senior.
Typically it sucks. They will use LC first for anything which is known in advance (saving SC for last-minute sick calls which LC can't cover). They also can typically convert you to short call X number of days per month, and they will.
So you're either flying or sitting SC. LC might be useful if SC is under-utilized and you don't want to travel to base and spend every weeks sitting in a pad.
