Wild 7: 3 builders, 2 bashers
Wild 8: 10 climbers, 10 floaters, 1 builder
Wild 10: 3 builders, 1 basher
The builders-only route for Wild 3 takes a bit of fine placement. You can get up into the first chain with a single builder if it's placed in the right spot. (Actually, there might be more than one position that works.) The other tricky bit is the one Yawg is struggling with - avoiding getting stuck in the ceiling.
