Taking the road less traveled???

I’m happy at my current job as a network administrator. I’m in charge of everything pretty much and I’ve got a great boss, perks, and a flex schedule. The only drawback is the stress level and dealing with some of the idiots in my company. I know that’s part of the territory but I don’t have to like it. My question is, I would like to either branch out into security or management. I’ve been offered in opportunity to manage a security group for a healthcare company. The pay is the same but it’s more management than technical. Actually the only technical thing they do is set up AD accounts and exchange accounts, play with group policy and that’s pretty much it….What are your thoughts on this? The pay is the same, the bonus is bigger although not guarenteed.
