Roger, how are things in FBKS now that the tourist season is over? This time of year was ALWAYS my favorite in Alaska.
Performance without shootability and stability isn't very useful. So you can expect all three attributes in the ACS recurve. It is fast and well-mannered.
I'm not gifted with well-developed subjective abilities, preferring to confine my observations to those things that are measurable and verifiable. However, the "feel" of the current prototype has that classic near-letoff sensation that a well-designed recurve provides.
Setting brace heights at goofy-low levels and building twitchy limbs in order to maximize speed isn't going to appeal to large numbers of customers. We won't do that because it's counter-productive to our business plan. Building a "me-too" recurve limb that doesn't offer more to the customer is also something that fails to excite me. I'd rather not offer one unless it's a step forward.
Test results of the latest prototype (now working on prototype #8 with Mike & Jason) is very promising. Simply getting a limb/riser/geometry design that works and shoots well isn't enough. We had that at prototype #1 (based on my multiple years of earlier prototyping). Changing one thing at a time and working meticulously through evaluating the impact of each change enables us to fully understand limits, envelope boundaries, and all the changes that maximize performance and stability without reaching said limits.
I'm comfortable that we're at a point where we can and will drive a developmental peg into the ground. While there will always be room for improvements and further developments I believe that the new ACS recurve will be at least as stable as any other recurve limb out there while offering outstanding performance.
A bowyer quoting his own performance numbers is always suspect. Consequently I never do that. It's true that I have extensively tested each prototype to understand the value of the design changes and am very confident about the performance level of our design. I have little doubt that our third-party test results will be very impressive in comparison with most any other bow. It will definitely allow most archers to drop down in draw weight and still shoot the same arrow the same speed. In my opinion that's one of the better ways to use performance.
