The Mako3 flies extremely straight with a gentle fade towards the end. It also glides really far and gives you a great chance to shape throws to the fairway. The Mako3 is an excellent, neutral-flying midrange that everyone can benefit from.
In Halo plastic you get a disc where extra care has gone into the details. It will often be a little more stable brand new and then slowly wear in to the Mako3 you know from the standard versions.
Note: small variations in the disc's appearance can occur because of the nature of Halo plastic.
