"Old School" Carbon Arrows

[Patriot-2000]

Getting back into Compound Bow Archery and by next year the woods with Bow in Hand.
I'll be shooting a PSE Spyder set at 29" Draw and # 45-50 with a Quatro Pro Rest. Trying to look into arrows and don't understand the numbering system ... Terminator 6025 , 5575, and 5025. I've been looking at arrow charts and a 300 or 400 arrow is what the charts say I need.
Anybody know how to read the longer set of #'s or do they equal a 300/400/500 ?

Nobody ... ?
Hopefully the Archery Shop will be able to point me in the right direction.

Who's the manufacturer of the Terminator 6025 , 5575, and 5025? I know Easton has the plain old spine number, .500, .400, .340... Carbon Express has a different system, a 4560 (which means 45-60lbs draw) and 6075 (60-75lb draw) and also a 250 and 350 numbering system. 250 means the spine is in the .400ish range, and 350 is in the .340ish range. Clear as mud? I found it so, too.

I know what you mean about being as clear as Mud. I appreciate your input and information. Just got my Bow in last Thursday, so I'll probably take it to the shop this saturday and get it set-up. I should be ready for the woods next season...

I'd go with Carbon Express 250 or Beman ICS 400.
Terminator arrows are made by Carbon Express...4560 would be good in the Terminator.
