I have 2 jackshafts that'll allow me to run a 2spd auto.

Should i go with a low gear and a high gear or stay single speed.
Low gear 9.5:1 for 22.5"tires ~ 11.4:1 for 27" tires
High gear 6.69:1 for 22.5"tires ~ 8.06:1 for 27" tires
~4100rpm is where the second clutch kicks in for high gear, and low gear would just freewheel.
