Yep..100gr Mags for me..been shooting them for a few years now.
I can tell you this from personal experience - The "field point flight" they advertise is only when your bow is tuned! They seem to be not as picky on the tuning as other fixed blade heads, but that doesnt mean you can just screw them on and they will fly perfect. Your bow still needs to be tuned, and your arrows still need to be spin-tested. Last year my bow was perfectly in tune and I still had an arrow or two that didnt fly straight - checked them on the spinner, and sure enough, they had a wobble. Squared up the arrow and they flew perfect.
I would suggest to you to get an extra pack of blades right away. Shoot your broadheads on each arrow and make sure each arrow flies good..pick out your good arrows you are going to use for hunting, throw the new blades on them, and you'll be ready to rock.
