Longer (mid-range ish) AviarX3 Recommendations

Hi friends. Putting the finishing touches on my bag for the upcoming year. Star AviarX3 is my stable-overstable putter and approach disc up to 230-250ish. Looking for a faster disc in the mid range slot (270-300ish) that has the same flight characteristics- torque resistant, pushing fade, resists turn, handles flex lines both fh and bh.

I’ve tried the pyro (too overstable and don’t like the hand feel) and the MD4/Solstice (like it for backhand but doesn’t handle the forehand flex well). Hoping to hear your suggestions. Thanks!
