I know you can't buy everything there, especially specialized hard to get stuff that they just don't want to stock,
I've gone to my local Cabelas store a couple time thinking that if anyone would have a 5/16 cable slide for my old Martin; Cabelas would. And every time I think that Cabelas should stock about everything under the sun I'm wrong. They have actually told me to go to Clelands, which is my local shop, more than a couple of times. Its a 20 minute drive to either Clelands or Cabelas, but the two places are 40 minutes apart, and it makes me mad every time they tell me to turn around and go the other direction. I've noticed that for a HUGE SUPER Store Cabelas archery department doesn't really come close to "having it all."
On the other hand, I do have complete faith in the people that work in the Cabelas archery department. I know a couple of them personally and they are really knowledgeable people (and I have no idea why they even take their jobs seriously when they get paid as little as they do.) And although I think their line of bows isn't spectacular they will properly fit and setup anyone looking for a new bow.
The whole reason we are having this conversation is because Bass Pro and Cabelas take a skilled job and only want to pay their people $8/hr without benefits to do it. So sometimes you get people that don't have a clue because the real people that know what they are doing, aren't willing to work for that kind of money. So I guess we'll keep having this sort of situation until these Super Stores figure out that good help is worth paying for.
