I had to laugh 5 pins or 7 pins? how about 25 pins? haha. I know guys that only have 1 pin, I've always had 3, and now that i've hunted outwest I'm considering a 5 pin. So I'd certainly say get a 5 pin, 7 I think would be way too confusing, even 3 or 5 confuses some guys, but 5 I think is pretty safe, from the center pin there will only be 2 pins up or down, witha 7 pin, now you have 3 up and 3 down from center, so like in an instant you say goto your 40yd pin....then its like which is my 40......ok my 3rd pin.....I think 5 would be much quicker to identify your pins than a 7, and would suspect more errors would come with a 7 than a 5. If you use a 5 pin at 20, 30, 40, 50, 60yds, how far do you want to shoot? then at 70 youll still have a good idea where to put your 60yd pin, do you plan to shoot past 70yds? even with 3 pins you can get away with 20, 35, 50 or 25, 40, 55yds.
