So for juggle you could use the jab strings into 2P palm, or a Dragon Lance Combo (3H+KP466P+K) but since you are not a fan of the 466P+K ender, the P+K standard version off DLC could still work, though can vary heavily in slope areas causing it to whiff or weight class.
Most launch setups besides the knee can be 33P, 66K (Stun initially or CH), H+K (Raw), 4PP+K, 3H+KP+K, and 8K. The juggle easier methods can consist of the palm or 2P into palm due to the small refloat.
