I practice with field points, but periodically insure that my broadheads are flying the same.
Never tried shooting BH's without blades. Hmmm, interesting. I may try it.

I've got to agree with ADAMS about the pins, at least for hunting. If I shoot using my 20 yard pin at 10 yards, I have about a 1 inch difference in point of impact. I'm not shooting any speed demon either - only 212 fps. That's too small of a difference to warrant another pin on my sight that will only help to obscure my view of the game I'm shooting. Just set up for 20 or 25 and hold a bit low for shorter ranges, and a bit high for longer. Experiment to see how much of a difference there is with your setup.

I've got a second pin on my sight, but right now it's only to assist with yardage estimation and acts as a backup to my primary if it should break. I haven't gotten around to actually adjusting it for a given yardage. Having too much fun shooting out 1" stickers at 12 yards in my basement. I'll probably eventually set that second pin up for about 35 or 40 yards, and just estimate for in-between.

Keep your sight, and the rest of your hunting equipment, simple and streamlined. Mr Murphy rules the woods.
