I did something like you did. There is a lip on the outer edge of the wing fillet, about 1/8 of an in. thick. I trimmed the rear of the saddle till the lip is a sharp edge, and tapered it to the front, so the wing is more parallel with the stab, essentially raising the rear of the wing by about an1/8 of an in. Added downthrust too. Now you can crank the throttle on at any speed and it goes in a straight line without climbing.
