Debating between large Student Loan Payoff vs continue investing with new law

Been lurking for a while and finally realized I need to get thoughts on my situation. 43 yo w current pregnant wife and one 1.5 yo kid (late start ha). $350k/year salary, currently $730k in a brokerage plus $430k in 401ks/IRAs, with $65k in HYSA. Only debt is house with 6.6% mortgage but do have $230k in student loans at 6.8% interest from law school (2011-2014). Have been on PAYE plan for loans the whole time, had been going off 2019 AGI with covid so about $900/month.

Original plan was to pay the minimum in loans and drop as much as possible into the market. Would pay minimum on loans for 20 years and they’d be forgiven (albeit with a huge tax bomb at end).

With OBBB legislation and PAYE repayments about to be done, now that plan is shot. Considering just selling some of the stocks and paying off the student loans in one big shot but tough to stomach that large of a hit to my brokerage. Have about $110k in gains but am realistic I can’t keep up 20% growth. On the other hand, these new student loans monthly payments plans are going to be at least $2k+/month minimum with interest starting back up. Thoughts? Thanks in advance.
