Jacob,
I haven't used Larry's hunt planner, but Iknow people that have and I've heard nothing but great reviews. I've bought a lot of gear through Larry (including a SOAR Levitator) and I'm always bouncing questions off of him. Like Magnum said, he's honest and he really is a top notch guy.
Kent Rotchy (owner of Rocking R Designs - Oar Saddle) did an archery huntsimilar to what you're planning through Larry last year and he had great success. You should contact him if you want a first hand account. Here's his website:

Larry (and most other folks for that matter) will give you all the answers you need for free, but you just need to ask the right questions. He sure won't tell you where to go for free, but he'll tell you if an area you've researched is worth a crap and what to expect.
Don't be fooled by a $3500 price tag.Price doesn't necesarilly equal quality. Get testimonials before you plunk down the pesos.
