If you opt for a 2pc try one with the Bow-bolt system, it is stainless steel and adds some additional centralized mass to the riser. Since you do not want a "longbow with recurve grip" like the Fox Triple Crown (excellent bow indeed), I would suggest something like a 2pc Bow-bolt configured:
Toelke Whip HS (with standard or perhaps classic grip), Java Man Falcon XL, Holm-made Goshawk or Kingfisher etc.
You also might consider a phenolic riser Whippenstick, or as an alternative to the TC one of Ron's Fox Traditional longbows with a phenolic riser and the brass/stainless sleeve system.
Bows like the Tomahawk or Black Widow that use the carbon/glass sleeve system are perfectly fine as a 2pc, but you have to rely on the riser material alone for mass as that sleeve system is feather light.
Steve at Northern Mist could also build you a phenolic riser Superior or Baraga, that would be really neat.
Call some bowyers and see what can be built for you.
