First I commend the many find responses offered to this important question. My only comment that has not already been articulated would be that I disagree with the thought that there is no limit to management and that it is possible for a middle-manager to rise to the c-suite. This no longer occurs which is actually a problem. The upper management ranks now consider themselves aristocrats and pay themselves accordingly and dispense with employees of all kinds in the lower ranks accordingly.
It also appears that there is a trend towards more experienced technologists. I am 42 year old coder and architect and I am often ping'ed with job requests even in this economic environment. I've done some management and speak often with management given my position and there opinions of management job prospects vis-a-vis tech seem to square with my opinion above. If you want to move to upper management you are best starting your own company if you are not a Harvard MBA. That's my two cents in any event.
I suggest trying management since it appears from your post you desire this. However, be prepared to abruptly change course again if you decide this is not your karma because project/middle management is extremely difficult and not highly valued by upper management.
In any event I wish you the best of luck. I truly do.
