I've heard about Tri-spine arrows, what's special about them and how will they benefit me?
Tri-spine arrows, such as the Maxima line from Carbon Express are the latest innovations in arrow technology and address a few of the major difficulties an arrow has to endure. As the name suggests, a Tri-spine arrow is made up of three different spines. The placement of the spine sections are different in the recurve and compound variants. Compound arrows consist of a weaker middle section and stiffer front and rear sections. The main purpose of this construction method is to manipulate the arrows flight, especially when exiting the bow. The quicker the arrow can settle down into stable flight the better the outcome. The strategic placement of the various spine zones allows the arrow to flex where needed for a clean exit but not be too tail happy. The
flex in the tail of an arrow has always been an issue for compounders more than recurve shooters. This is down to the fact that the forces are far greater and more direct into the arrow from a mechanical release aid than off the fingers, not to mention the bows are more powerful and snappy.
The Tri-spine recurve arrows are stiffer in the middle than the front and rear sections to tame the paradox, whilst maximising fletching clearance around the rest and pressure button. Another arena where this new technology really comes into play is indoor shooting. The difficulty when shooting indoors is that there is very little time from the point of release to the arrow hitting the target. There really isn't time for the arrow to get settled. Archers and fletchers alike go to great lengths to slow the arrows down with feathers and heavy points etc. to maximise quick steering and stability. These new arrows are a massive step towards addressing the indoor & recurve related issues and I'm sure that they will quickly gain favour with shooters who desire dedicated recurve arrows. Theorectically, these arrows should be very easy to tune as long as you have selected the correct spine. The Tri-spine or RZ series of arrows are full carbon arrows. As usual, before purchasing any of the outdoor variants it's worth checking with your club to see if they have any policies that prohibit the use of full carbon arrows. This is especially common if shooting is conducted on a shared-use field.
