A model 66 is what I've traditionally carried out in the woods. I recently picked up a model 69 4" with an eye on woods carry because of an increase in wild pigs. Some of them are pretty good sized and are supposed to be tough critters. I figured bigger is better, even with one less shot. Both guns fit in the same holster, so I just have to pick my flavor of the day. With solid lead bullets, I think either will do the job on anything I run into.
