While I'm not arguing that Reflex bows aren't good (they are, in fact top notch -- just like the Diamond line produced by BowTech; it's often utilized by a top manufacturer such as Hoyt or BowTech as a means of reaching the masses through a lower price point coupled with the ability to sell through catalogs).
However -- just because a person endorses the bow, that doesn't mean that they are necessarily shooting the bow you can buy off the rack. They may, but they may not be as well.
Here's a quick example, and it holds true for a myriad of industries: I've got some background in the motorcycle industry (though that's not really necessary for uncovering what I'm about to say...), and as such I became fond of an event called supercross. The top stars are all given what's referred to as "factory rides", and sponsored by Yamaha, Honda, Kawasaki, Suzuki, KTM, and so on.
Upon first glance, you think your favorite personality is riding a bike that you would love to go out and buy at your local dealership. But dig a little deeper, and you'll find out that his "works" bike costs upwards of $100,000 to build, and is complete with titanium footpegs and all. Is he riding -- and more importantly, promoting -- the same bike you can go buy? No way. The biggest thing you'll have in common with his bike if you go buy one to "be like Jeremy" is the color scheme.
Now, does that happen with stars in our industry with their bows? I'm nationally sponsored, and I shoot the same equipment that rolls off the assembly line that you can buy at the local shop. Is it the same when it comes to superstars like Chuck Adams? I don't know. Probably.
But... it
is something to be aware of when using the line "So-and-so endorses the product, and if it's good enough for them, it's good enough for me!" Just keep in mind: What they're using and what you're using might not necessarily be the same product.
