Tradcat...
I'm probably not any help here with my view....
I shoot both...
Some of my bows seem to "like" 3 under while others "like" for me to shoot split....
If I were a serious target shooter...I'd pick one and "go on with it"....
However...I'm an archer/hunter/experimentor...and I love experimenting and having fun....for me that means trying "everything"...
Friends of mine that want to help me "improve" my shooting always tell me to pick a style...technique...whatever...and stick with it and build upon it.... There is a lot of wisdom in this thought if the only goal is to shoot high scores and collect lots of game (animals)...
Again...for me...the joy is in "learning/experimenting".....
Don't sweat the loose
Have fun with it
...not much help....right!?!?!
LOL!!
