I need a 430 mast for my least used sail size 5.0
The Chinook epoxy masts seem to fit the budget. Are they any good?
Less responsive than carbon but still decent enough?

No.

Given how luff lengths are trending a 430 is where I'd invest in quality.

Sail sizes for Montreal tends to be 6 and up with the wind we get here

Buy a quality, used RDM.
430 seems very long for a 5.0, lots of 6-7m stuff rigs on them now.

You have to ask yourself, who are the pros using Chinook masts? As far as I know, none.

If you could care less about what the pros use, I would look at the bend curve. While most masts these days can be viewed as constant curve, there still is a range from hard top to soft top designs. Much depends on the characteristics that the sail designer focuses on. A real neutral constant curve bend is arguably 76/64.

You have to ask what's best for your 5.0 sail. I don't know whether that is your smallest sail, but as sails get smaller, it becomes important to have the right mast when the conditions ramp up.

cuz it can stick out the top with zero on the bottom
also my least used sail - for newbies mostly

I stand by previous statement. A quality RDM 430 will be good value for years to come and can likely rig your next size up.
I see Nolimitz going used for about what you are planning to spend on that Chinook.

FYI Chinook RDM 60 and 90 percent masts are actually quite good and at least one sponsored sailor rigs them with HSM sails. They are just slightly more flex top than true constant curve.

Don't the retros need an SDM?
Out of interest, what's so bad about epoxy compared to carbon (except for weight)?
I already have a 460 just doubt the 5.0 rigs on that well even if the sail does have a hole in the top sleeve

I have Chinook RDM 60 & 90 in both 430 & 400. They're fantastic masts, better than the Powerx RDM carbon masts they replaced. The only difference I notice is that the 60 is slightly heavier than the 90.
I would not buy the epoxy mast: go for the carbon, they're still really affordable.
