Uh oh, I've got a funny feeling about this...
When I bought this mast, the local shop was advertising it as a constant curve
mast. The warning bells were ringing then and I should've listened, as I'm
well aware of North=flex-top rule. However, the sticker on the mast has me
a bit confused. It is a NIMS (North Intelligent Mast System) 90 1-piece
superlight carbon mast. The bottom claims a DIN of 7.8 and an MCS of 3-4.
Under the DIN number, there is a graphical display of a flex-top mast with
a label saying "Flex Top", and under the MCS number there is a graphical
display of a constant-curve mast labeled "Constant Curve".
Help me out here, guys. Obviously, my understanding of MCS and DIN numbers is
1. Is this mast constant-curve or flex-top (my guess is flex-top)
2. What exactly does the DIN number refer to?
3. What does the MCS number refer to?
4. Is there a relationship between DIN and MCS numbers?
5. Should I march down to the shop where I bought the mast and demand that they
sell me a constant-curve Fiberspar carbon mast for the same price ($199)
I paid for the North carbon mast? :-)
