This is a great game by the way
A few options/ thoughts if they help.
We used to play you were “forced” to call at 400+, and you had to ‘win the hand’ to win over all. (Unless both teams at 400).
Being able to select if you want to call Bells or not (you may not want to if you will bate anyway)
If you and your parter both have runs with same high cards (eg both AKQ), they should not cancel as one person would ‘forget” to show if playing in person. If you and opponent, they would cancel.
Only real concern is randomness of deal of high-cards. Finding opponents get about 75%-80% of A /10 or win them.
Wish my parter didn’t always lead trump if I was forced to call and I may not have J.
