For once, I have to disagree with Ray: my BG pack is the only one I've had on that I could shoot comfortably while wearing. I have no issues at all reaching into the BG packs and finding what I need and prefer their internal setup with a few small pockets etc. and a large internal area to one with multiple sections. The BL fannies do not have an expandable game bag like the Lost River or First Trip, you get the BL's as they are, instead of fully customizable like the BG's. Want 2/3/4/? pockets on the belt section, no problem; want them a specific size, no problem; want bigger detachable accessory pockets, no problem...Angleo can deliver exactly what you want. I like wool, BL doesn't offer it, I like Predator camo, BL doesn't offer it.
The BL packs are a great design, well built, and with a great warranty (I'd buy one in a heartbeat if I couldn't get BG products), but the BG packs are at least their equal in my opinion.
If I were to get a BL, and I really liked the mulitpocket approach, I'd look at the UltraDay. This pack is the most tempting of their lineup for me.
As with bows, I suggest you get one of each and give it a try. Sounds like the BG is already on it's way...I'd get a BL from somebody to try out at the same time and make the decision with both in front of you.
