Maybe I didn't interpret the original question right. If you're talking about mass weight then just about any properly spined shaft with a 100gr point will be heavy enough. Plenty heavy. And that doesn't even mean nocks, inserts and fletching have to be added in.
If you're asking about spine then I hold to my original answer. ACC 3-28 would be pretty close. I have shot 3-28's at 63# and 27" arrows at 27" draw just fine. If you have any issues then I would look no further than www.eastonarchery.com
and check out their spine charts.
I'm not familiar with Carbon Tech.
