That is really good, like nats first place level, but you're from Cali so not surprising. Any tips from your tower?

I'm starting to wonder if the bonus is really worth the trouble. I've seen/heard of several top-level towers without the bonus.

Yup, so have I.
I think, but am not sure, its close. Posted some calcs a while back indicating it is, but continuing to think. I'm sure it is for a ladders and Xs approach, but may tip the other way on other bracing configurations. A key limitation the wider stance introduces is longer bracing toward the bottom, meaning brace pieces need to be stronger (i.e., heavier).
So when/if new insights, I'll post.

I feel like bonus really isn't worth it, because when you get down to so 5,4 grams, a slight shift in the denominator will dramatically impact the score, as in just moving the numerator up 2kg, its really a hassle. Felt bad about and it may not be worth it for only 2kg.

What do you gues use for the legs? We use 1/8 squared balsa but I feel like it's inadequate

For the most part, people stick to 1/8, or 3/32. The thing is, if you go above 1/8, your going to have to use a really low density stick to achieve high scores, using a higher density, lower mass stick may prevent lots of problems such as the wood and glue tearing off when pressure is put.
