You're getting great diverse advice.
One thing to add to your considerations is once you get into a league, what do your intra-divisional and extra-div opponents look like?
If you are the only extreme hitter park in your div, and your div mates are all pitcher parks, in addition to a few outside your division, you may have a rough time winning the division, even if you get the players you want. It doesn't mean you abandon your strategy for up to 50% of your games (that would be a disaster), and we are not talking neutral parks or just a few parks, but if many of your opponents are tuned to their extreme parks and you to yours, it's a stalemate. Of course, you can take the angle you will just do it better than they do at home...which is a strategy too.
You don't need much differential to get an edge--maybe if you are a hitter park in a sea of pitching parks, it is adding a true #2 hitter who still has some power but can get hits and move guys without DP balls. Or getting a few power guys who aren't station to station on the basepaths. Yes I am one of those crunchers sometimes, which is why I don't like playing more than a team or two simultaneously...so I get a feel for the R/L slant for singles and HRs by park, give it a weight based on division. Then I'm looking at if I throw a lefty or righty starter, am I seeing LH bats or RH bats mostly? That may give me pitching options I wouldn't ordinarily consider. Many times there is no need to adjust, but sometimes a perfectly well constructed team for your park doesn't win much more than half the time and that is where I'd start looking at why.
So with that said, for the team link shared by freeman, before I took a recipe away from it, my question would be where is the league link, then we can see how universal or proprietary the team is
. Same idea as you would adjust with extreme lefty/righty parks.
Though even without seeing the league--that team adheres to much of the basic tenets nomadbrad and freeman brought up.
Cheers
