TB or OBP?

For starting pitchers-on base percentage or total bases?

Depends on stadium, league cap

In what way?

The higher the offense of the park, the more you want low on base pitchers. The pitchers parks you will give up some on base to take away hits and especially extra base hits

In a bomber park where HRs skyrocket does it make a difference whether that runner got on via a walk or via a double/triple? Scores either way. So one may argue in a bomber park OBP more important to make those HRs solo shots as often as possible.

Reverse for an extreme pitcher park where HRs are reduced and it takes multiple hits and/or doubles/triples are more likely to be needed to score score runs and walks are more likely to get stranded and one might prefer to limit total bases on the pitcher card. Walks more likely to get stranded or taken out in a double play. Doubles and triples may become more important.

Though any simplistic rule/guideline needs to be tempered with all relevant factors.

Exactly what I had in mind.

Replace bombers park by no-cap league, and the same logic goes.

Agreed and good point. With high cap leagues facing HOF lineups walks are going to get punished off the hitter cards. You want to limit Ruth, Bonds, etc to solo shots as much as possible.

Should also be noted that in high cap leagues there should be sufficient budget money to target pitchers who excel in both low OBP and low TB. When you can afford to spend 9-11 mil on starting pitchers you should not be having to choose between the two strengths. Just eliminate everyone who is weak in either area unless you have good reason to accept a tradeoff.
