22yo, $28k Roth IRA. Rate my 60/20/20 "Aggressive Global" Portfolio.

Hi everyone, I hope this is the right place to pose this question.

​I’m 22 years old and currently have about $28,000 in a Roth IRA managed by Edward Jones. After realizing I’m paying ~1.5% in annual fees to lag the market, I’ve decided to pull the trigger and consolidate everything to Fidelity to self-manage.

​
​The Proposed Portfolio (Fidelity Funds):
​I’m planning a 60/20/20 split:
-​60% FSKAX (Fidelity Total Market Index): My core US foundation.
-​20% FTIHX (Fidelity Total International Index): For global diversification/safety net.
-​20% FSPGX (Fidelity Large Cap Growth Index): My "tilt" to overweight big tech/growth for the next 10-15 years.

​My Rationale:
-​FSKAX gets me the whole US market.
-​FTIHX at 20% feels like enough international exposure to avoid being 100% US, without dragging down returns too much if the US continues to outperform.
-​FSPGX is my "aggressive" bet. I know it overlaps with FSKAX, but I want to double down on growth/tech while I’m 22.

​My Questions for you:
-​Is the 20% tilt to FSPGX overkill given that FSKAX is already tech-heavy?
-​Is 20% International (FTIHX) a good middle ground? I see some people say 0% and others say 40% (market weight). I’m trying to find the sweet spot for maximum growth.
-​Are there any specific "gotchas" or better fund equivalents at Fidelity I should be using instead (e.g., FZROX vs FSKAX)?

​Thanks in advance for the feedback!
