In many ways open pollinated crowns are less fussy (and cheaper), but one of the issues with them is that you may get a female - which produce more seed and less spears. If you grow from seed you will definitely get females, but even if you don't, some feral seed will arrive and hide in your row.
The usual advice is to dig out anything that shows berries, but it can be really hard to get them out without damaging the crowns around them.
I prefer to mark them with a brightly coloured stick or ring, and cut every single spear they make until they stop producing - so you get a few spears a week when you usually don't get any. Even a big well-established female will give up after 2 or 3 years of relentless cropping.
Win-win!
Cheers.
