You could build some Easton 6.5 at 29.5”, 50gr brass with 100gr tip. Wrap and 3 blazer vanes. Use the included microlite nock and be right at 470 TAW and achieve what you’re trying to accomplish. They have 3 different grades of the 6.5 also. If you want lighter TAW you could do the Sonic 6.0 in a 300 same as above and be right around 450 TAW.
