Yes Doug, for that kind of work an overbuilt axe with a fiberglass handle might be a better option. When it comes to demolition, I'd rather have a Pulaski, maybe a big crowbar and/or a heavy maul.
BTW, another very important factor to consider as far as axes go - ergonomy. One of the reasons I truly love my Gransfors Bruks small forest axe is that aside from an excellent head, the handle is absolutely perfectly shaped. Wherever and however you grip it, it allows full control whether you do heavy chopping or finer work like carving. Most other axes on the market, either wood or fiberglass handle, fall way short in that department.
A quality axe truly is a joy to handle. People tend to forget there is a lot more to a good axe than just decent steel and hickory. Everything has to be tuned just right - balance, handle length and shape. You really have to try a high end axe like Gransfors to appreciate the difference.
