The question of whether you can/should transfer more weight should be based on measurement, not feel.
X = Front wheel well height with no trailer
Y = Front wheel well height with trailer attached, and WDH engaged
For anything less than a 3/4-ton truck, you want Y to be as close to X as possible (or equal) without actually being lower than stock height. If that's where you are, then you are optimized. Transferring more could put you over your front GAWR.
If Y is more than 1/4" higher than X, and you want to transfer more weight, you may not have the WDH rated high enough:
