If there's four in your group and one of you gets drawn, all four of you are in, so I'm not sure how solo increases your odds? If solo increases your odds, I wouldn't think that there would be thousands of folks with 20-30 pref points for elk and the Wichita Mtn deer hunt.I have found that applying solo increases your odds. Think about it, one spot is easier to fill than four. I am ditto be drawn every other year or so and always apply solo. I also only apply for doe hints which helps.
