So SEW, you have not seen any adverse effect from parallax at 100y? And you find 8x to be enough mag?
I like your idea for a dial-free 100y reticle, but they are so dependent on magnification being set to have the proper reticle subtensions. It pretty much locks you into a certain mag and with faster bows, this means high mag which I don't want want at close range. What I like about the HHA is the ability to change magnification as the circumstances dictate, I don't mind the range-dial-shoot method, but it has two serious drawbacks: the extra movement and it can be time consuming. But with the speed I'm shooting and the ranges I will hunt, a 30y zero gives me minute of deer accuracy out to 40y.
Side note: here is what I'd like to see to eliminate what I deem the HHA's adverse effects, namely the extra weight and higher cheek weld it necessitates. Eliminate the scope rail and integrate the picatinny rail with the top of the tigger box. This would reduce weight and lower the position of the scope. An arrow retainer would be fastened to the underside of the scope mount and an ADF could be integrated into the trigger unit itself. (Patent Pending)
Here is what I would buy for an HHA setup if money were no object, (my wife reminds me that it is). The Leupold VX6 in 2-12x40. It is like getting three VXR scopes in one, but paying for those three scopes and only getting one
It has an amazing 6x zoom, so it offers the greatest amount of variability. It's like a 2-7x, 3-9x and 4-12x in one package and it features the Firedot which I like a lot. It's a long scope, but weighs in around 16oz and you can top them off with the Leupold Custom Dial System to tack on more elevation than the HHA provides. It sounds perfect for my application, but very cost prohibitive and it's not an adjustable objective scope.
