Disc brakes may be the future, but they're completely unnecessary on a TT bike in most instances.
That said, I'm struggling to see how a 105-level P-series came out $1000 more than a 2020 Trinity Advanced Pro 1, even with a wheel upgrade. We're talking a $3200 MSRP vs $6200. You should be able to buy a entry level P-Series, put good wheels on it, a power meter on it, and still come in less than a top-level Trinity.
