Welcome! You look in good shape and I'm sure you'll enjoy spending even more time out on the lake. I don't want an answer to this since it's personal, but since you mentioned you were both married before, are either of you planning to leave "your" money to kids from the prior marriage? If one of you were to predecease the other, would a portion of the retirement money go to someone other than the spouse?
These are all personal choices, and there is no "right" answer, just make sure you have any possibility considered in your plan. Also, make sure you have the right beneficiaries designated on all your accounts etc.
