While dropping to a disc with less weight may help you reach the intended flight characteristics, you'll have better luck dropping to a slower disc which has a lower velocity requirement. In your case, throwing something slower like (and staying in the Innova family) a Valkyrie or even a Leopard would potentially have similar flight characteristics.
Of course, this is all dependent upon you generating spin or "snap" on the disc, which is often the reason discs don't fly like they should, especially with beginners.
