Yikes, contact width line...

Would tower chimney still be viable? With the new bonus, how heavy will boomis be now? Aiming for a safe device mass, it might be upwards of 8, even 9 grams early in the season (maybe more 2k+ scores?)

Wdym yikes? This effectively neutralizes all super wide boomis (which weren't very effective ngl) and paves the way for a chimney boomi meta to be rampant this year. (This years rules make boomi way easier ngl) Any "good" chimney boomi would be well within 8cm gap the vertical contact lines are giving you. As for the boomi weights its gonna be an interesting distribution of weights... I was able to get boomis that weighed 5.8-6.4g to hold 12-14.9kg last season so maybe the most competitive boomis end up in the 7-8g region and would hold 15kg sooo scores would definetly be over 2k (Div C). I'd expect national boomis to reach near or more than 3k as people figure out how to boomi (Again for Div C). Right now all teams that got a strong design made that topped 2k last year will be well ahead of most teams as these teams are using 2 types of designs mainly (Which shouldn't violate the rules).

Uhhh unless I completely read that wrong the boom must be OUTSIDE the 8cm lines, not inside. So they would have to be wider, not skinnier.

Welp the wording suggests that... In that case boomi is 20 times harder... Good thing I ain't a competitor no more!

Do the rules specify that there is a size limit for the portion of the boomi that passes the contact width lines? Does the whole boomi have to be at least 8 cm wide? If not, could we not just create an 8x15 cm balsa rectangle to place at the end of the boomi that contacts the testing apparatus?

The rectangle would need to cope with enormous amounts of stress especially at the center of the stick.

This is correct

I suspect high-performing boomilevers will be narrow at the top, widen towards 5 cm along the tension pieces, and widen from 5 cm to 8 cm again along the compression part.
