If I ever need a new system I'd probably go for an in boom cascade. It's more work to setup right but it is cheaper to buy and cleaner.
How do you figure?
Most boats now use a direct block to sail connection. This means the sail cut has to be boat specific, but the boom can be very light as there is just a minor compression load on it.
To go cascade you now have all the loads being sent into and through the boom plus the added compression load from the internal cascade. You need a bigger stronger boom for this plus the added room needed to mount the cascade.
You still have to buy 6 blocks and you would still want 1 with a ratchet and cleat. The inside cascade blocks use little line so they are smaller but in the end that does not save you much price wise. If the purchase is the same you still have the same amount of sheet sitting on the tramp and this is what IMO is the messy part of the sheeting system anyway.
