First as what I have seen from your product clips, that you guys have put alot of time and effort into your company. (and money too, from what I saw of your machinery in the "Birth" clip)
Secondly, for visiting our lil ole' Kansas forum, and not only advertising, but actually reading the posts and giving feedback.
The Sinus is a great disc, reliabilty at its best. with the added speed and stability, I have been able to put it lower on long approaches than all other P&A's and without too much skipping or skidding.(when I miss, which is quite often.) Sinus AP is perfect, but for putting I would preffer the SP, although the rim is harsh on release. Maybe leave the AP as is, and add a big bead to the SP? That I think would help for smoother release.
I plan on picking up the others and giving the test run shortly, Congrats on the company, and as I have seen so far, The great customer support.
