RE: bowtech commander or gardian
Shoot them both, plus any other bow you can get your hands on, and then decide for yourself which one strikes your fancy more.
The commander will be a little more stable. However, I haven't found any problems shooting my Ally out to 60 yds at 33.25" ATA and I took 2 years off from shooting.
I was leery of the short ATA bows but after shooting for 5 months don't have a problem with them at all. Practice as much as you can and work on yourgrip, release and formand even the shorter bow will shoot great.
