@MHSCheercoach My senior year of high school we only had 5 girls, so I feel your pain. There are few stunts that I can remember that we did.
First one we called a "show kick" because it was kinda like a cross between a swedish fall and a show and go. The flyer grabs the main bases shoulders and puts her left leg in an arabesque that the side base grabs at the shin and ankle, dip, then go up to the swedish fall position for a hot second, then instead of going to the ground, the flyer brings her right foot down to the main base and the side base steps in and grabs the left foot to be in a load in, dip, then go to a half/extension/whatever. During this, the backspot helps toss up from the flyers hips/upper thighs, then grabs ankles/rear back in the load.
We also did a lot of half twist cradles, where the flyer would half twist so she is caught by the front spot and the bases and the back just grabs feet, with a back walkover out facing the crowd.
We also did a lib at prep level with a shoulder sit hitch, but what was cool is how we got into it. We had a flyer be the side base, go to a prep, then a base would go underneath the flyer basing, everyone would dip, and the base would stand up so the basing flyer would be in a shoulder sit holding the other flyers foot creating the hitch.
The knee baskets also reminded me of basket-ups. You just load in like a normal basket, but instead of throwing super hard to do a trick, you toss and grab the flyers feet at an extension.
Hope this helps! If you need any clarification of anything, let me know!
