Rebalance 401k, 38, $250k - Expense Ratios vs. Higher Performing Fund

Realized the funds I am in have an ER of .4-.65 and are performing at about a blended rate of 17% this past year. There is a “set it and forget it” fund (JPMCB SmartRetirement Passive Blend 2060 Fund CF30) that has a .46% ER fee and outperformed my choices by about 3% (20% returns in the last year). However, I am realizing how much money this will cost me 20-30 years from now due to ER… The only low cost funds that are available from my employer (through Fidelity) are the FID 500 Index (.015 ER) and FID INTL Index (0.015), which have performed at 17% and 31% respectively in the past year (INTL had a big year, but 10yr return is 8%). I am considering just putting 75% in the FID 500 and 25% in the INTL Index due to lower expense (.015 vs .46), but the higher returns of the JPMC fund have me second guessing… Thoughts?
