I can't think of any ramifications other than maybe you can get more coverage for less money the higher you go if you stay with the same company. Does that make sense? DH and I have plans through one company, then we each have plans through our work. Honestly, life insurance is one of those things that I don't think you can have too much of. People hate to think about it, but if you ever are in that position you will be relieved.
My best friend's dad died when we were 8. He was 36. He was mowing the lawn and had a massive heart attack. We had JUST left their house to go to the town pool. In fact, I remember hearing sirens as we walked. Her mom, an RN, performed CPR on him but he was gone. He SOLD life insurance for a living and was his own best customer. My friend's family was financially all set, and to this day she has a trust fund that gives her a monthly income. Her college was paid for and she bought a cute little house by herself. It is no substitute for her Dad, but I'm sure that he took great comfort in knowing his family would be provided for in the instance of his death. It happens.
