Stack-off ranges become narrower, so you also must consider avoiding reopening the betting with hands (https://www.casino.us/poker/strategy/poker-hands/), that you really do not want to be raised. Another specific point when transitioning from 100BB to 150BB is that a preflop 4-bet in a heads-up pot with standard open sizing becomes larger. With 100BB we typically 4-bet to about 21-23BB to avoid committing to the pot. But with 150BB we can size up and still retain the option to fold to a 5-bet.
