What barrel to pick for a pencil grip?

[The Chosen One]

I'm currently using The Harrows Quantums just because they are rear weighted which I did some research on would help me because of my grip, just think all of the rear weighted darts are not long enough for me. I feel I have more control with a longer barrel the best barrel I played with was the Target Agora's just cause I could stack them with a medium stem and slim flight. I don't like my darts going in tail up
