RE: Velocity stack required for this?

All aerobatic planes can cause you to require a change of clothes if they are not set up right. Get the CG and lateral balance right, use the recommended surface throws - dial in expo to soften them too. If you are nervous, you will be jerky on the sticks. I know it sounds like a contradiction but you need to relax even if you are nervous.
The most important single thing is power/speed management. Don't glide land them. Do a proper procedure landing, decreasing throttle gradually. Don't just chop power. When on final be gentle on the sticks. Use your rudder to line up, not ailerons! Adjust sink-rate using throttle - gently, don't chop! Just before touchdown you should be very near idle.
CAP's can be a pleasure to fly. Even though they are not my favorites I still keep one around because they can do the most awesome snap-type aerobatics. Thats why they also have a bad reputation. Plan ahead for your manuevers and don't just bang sticks. You will get to love the precision and the CAP will make you a better pilot.
Let us know how it goes.
Safe flying!
