Red dots can be an excellent choice.I have shot a Pollington Red dot for 3 years and love it.Just carry an extra battery [although I have never had to replace mine yet]. Mine is mounted ona Swithback XT @ 60 lbs,and sighted in at 20 yards with Goldtip XT Hunters and 100 grain Slicktricks.Good to 35 yards with no holdover if I do my part.
