Switching to straight braid in milfoil/hydrilla will be a good move even if not matted. The weeds will disguise the braid, you won't loose bites. Braid gives you better feel of your lure and will contribute to you not getting gunked up as much either. With stretchy mono or FC you will get that elastic behavior of the line and it'll snag up more weeds.
Straight shank hook, hide the point half way back into the plastic. Then when you fish it in the grass move it easy through the weeds. With the braid you will be able to feel it out and have good control of you plastic so that you won't be "setting the hook" into every weed getting snagged.
