If you have the arm, Bosses are actually less stable than Destroyers once worn in. They tend to hold their turnover lines longer. Wraiths are the least stable of the bunch and Destroyers tend to be the most stable out of the three molds. However, with PLH differences and other variations, there's no telling what you'll get if you just pick one up off the shelf.
Finding the right disc is going to be the case for every single company out there, so that's not to say Innova is the ultimate offender of QC. Every manufacturer has variations in PLH and dome.
But back to the OP - the differences I mentioned are there if you have 400' of distance, and also break them in. Otherwise, Wraiths are a great place to start if you have 350' of power. Below that, stick with something slower.
