Several things, actually. Like you, I'm going to a much faster set up, 320 fps w/ a 355 gr arrow. Why? Because I can, plain and simple. I still get TERRIFIC KE, and I'm just not worried about it.

Tighter scent control. I even wear rubber gloves when handling my clothing during the washing process this year, and wash my towels and such in unscented soap as well. I've not done that before this year, but details make the difference. I also bought a scent lok suit.

I'm being much more meticulous w/ my entry/exit routes this year, the reasons are obvious. Also, I'm going on the hunting less, but more effective strategy this year. Some of that has been by my choice, some not, but it's all working together.
