You could have your cake and eat it, too - a deflex-reflex (or is it reflex-deflex) longbow that LOOKS like a D shape longbow when strung. Meets all the regs for the different competitons, if that matters. Go with a 21St Century longbow or a Fox triple Crown. Very fast, easy to shoot and STABLE so if you are an accurate shooter, you tend to hit what you aim at, most of the time.
There are a lot of great bows out there - I kinda like shooting bows without much hand shock (some people call it a thump) which most conventional D-shaped longbows seem to have for me. So I like my 21St Century.
