Aviator 25 - I don't suggest to move the CG more back then applying spoileron. Spoilerons are better for slightly nose heavy as per your OP...

If you move the CG more back it will makes more difficult to land. Most likely worse on windy. You've experienced to stall when you move your CG back and if you activate spoilerons you would stall more. Flaps would help you to increase lift but it will reduce your authority to your plane. Spoilerons may not be applicable anymore with your present CG but I may be wrong when you determine some parameters including MAC of your plane.
