Hi mate, first of all well done on helping out and becoming a bit more educated, if only all players would do this!
The problem is every groundsman has their own way of working and their own methods they've developed over time. We all think our way is the best and only way to do it and anything else is the wrong way! Ask 10 groundsman the same question on pitch preparation and you'll get 10 different answers!
If I was you I'd visit your local ECB premier league club and have a bit chat with the groundsman, every square and ground is different so advice given to you might be totally wrong for how your decks are constructed. Get someone who can give you advice which is specific to where you play. Even better still get yourself an ECB county pitch adviser out, it'll be well worth the small fee and you will get a lot out of it, they will point you in the right direction!
