Thanks guys. Great feedback! I'm currently using the Spot Hogg 7 pin, hence the clutter. Not a huge issue, I do well with it, but if the sun is in my face and the target is in the shade I have a hard time seeing the target because all the pins light up too much. Plus I just think I can get more precise with the longer shots. Thus far I haven't had to shoot at game past 55yrds (yet), most are 20-25yrds, but I like practicing at longer yardage and would take longer shots under perfect conditions.
3rd axis is a requirement for the next site. When hunting mule deer and sometimes elk there are too many steep angle shots.
I'm debating if I should go the three pin slider (seems most popular) or single pin (set at 30 yrds, which should be easy shooting with no adjustment from 20-40yrs hold under/overs). Food for thought.
