a bow with slight R/D shape...
The Robertson Stykbow longbow is my choice but my Mohawk Sparrowhawk is very close second.
The limb shapes and riser design on both are phenomenal..comfortable, natural grip....the bamboo cores on these bows draw so smooth is unbelievable compared to my other longbows. The release is soft like butter and they cast a heavy arrow with authority.
I shot a nice hog with the Mohawk and have a new Robertson on order...but will keep the Mohawk.
Lots of good bows out there for longbows...but for a longbow that meets my idea of what they are all about is one with a D shape when braced....64" or longer in length.....one piece or a two piece (never liked looks of the newer 3 piece setups).....that have a large portion of working limb and a very smooth draw past their measured weight.
Slight reflex in limbs unbraced....but must look the part...be a pleasure to shoot...and really love the heavy arrows...light in hand, natural in grip....and a beauty to behold.
I go for ALL AROUND performance and beauty rather than just focusing on one thing.
