Have a DF800 FW bought last year. Very happy

Wondering about the force needed to set the main sail.
Even with the 2 speed winch it takes a lot of muscles, which I fortunately have but my wife doesn't. I have checked that nothing is blocking the sliding of the mountings and also lubricated each plastic main sail mounting with silicone.
And just hoisting the halyard is not posing any resistance what so ever.
Did switch the main halyard and the genoa halyard when raising the mast, but again no resistance.
It's a fairly new main sail and pretty heavy - but is it SO hard - like giving it everything I got?
Any experience??
Thanks,
Per
