For the money, I can't think of a better carbon arrow. They have the same straightness as the CX and Maxima series, yet they sell for 30 to 40 bucks less. They are 9.1 gpi for the 6075's. Here's the specs.

TCX nocks. Straightness of ± .0025". Weight tolerance: ± 1 grain. 9.1 gpi. .300 diameter.

They sell for around $80 / dozen. Not bad compared to Maximas.

I really like these. I've been impressed with all of the Terminator Select series arrows I've used. Anybody else use these?
