Well, you could go on knifeforums and ask Mike directly what he thinks would suit your intended use better. The B-1 is a pretty straight knife. The Foxriver has a bit of a negative rake angle to it. There is a lot more to a knife than simply being "overbuild". And as for overbuild: BRKT has long been a favorite among the "woodcraft" crowd and not only their heavier build models. For many the modestly build and very affordable Settler has been a favorite.
Sorry, didn't see that you had already pulled the trigger. I am sure you will be very happy with your purchase. Especially when taking fit and finish into account, there is nothing comparable within $100 range. And yes, DLTTrading is great. And the customer service of BRKT is absolutely amazing.
