RE: Seated or Standing?
Altough I don't use a climber , I can take a shot seated and standing it doesn't really matter to me.
If I see the deer coming in and I have time enough to stand then I'll get ready for a standing shot but if the deer are within twenty yards or closer then I'll remain seated and get ready to draw.
Practice is the key to making good shots seated or standing just remember to bend from your waste to get the right angel.
