how long do the poly systems last ? everywhere i speak to say its last 1 to 2 mths max , is that true! i currently get 3 mths with my lace system , but i can not afford to be buying a new poly every month, that would be insane.
Pre Covid I was getting 4 systems per year so similar to you. For the last year I've rotated between 2 and they are both in pretty good condition, they have had less exposure to the elements though.
I've taken more care of these 2 to see how long I could get out of them and I'd be comfortable at pushing 5-6 months now.
