A pyramid recurve is definitely an option. Each design has its benefits and drawbacks(like everything else) but there is no reason to use both methods in a single bow design. A pyramid style bow evenly distributes the stresses through out both limbs making it more efficient. Adding recurved tips isn't necessary with a pyramid design but isn't necessarily unorthodox. Recurving the tips on a bow(almost any bow) will add more performance but it will also add more stress. Its all give and take. Pat
