Debeer head with a harrow shaft-are they compatible? and TOS?

Im looking at a debeer head, either the tempest pro, nv3, intuition, or possibly the stx crux but I want a tapered harrow shaft. How do I know if they are compatible cause I don't know what TOS is(some of the debeer heads are only compatible with TOS shafts) is TOS like stx 10 degree angle or.....?

Answer
You got it.

The 8 degree Transfer Offset System (TOS) moves the offset from the head to the handle for improved feel.

Check with your equipment distributor to make sure, but I believe that as long as your debeer head is not a TOS only head you should be ok.
