I'm no fan of long term sheets, but IMO, this term sheet doesn't just punt that term to definitives; it gives me the expectation that all investors will receive "major investor" rights without dollar or ownership thresholds. Specifically, I feel that way because the "major investor" rights (ROFR, co-sale, pro-rata, info) are are in-line with anti-dilution and registration rights, which are typically afforded (in varying degrees) to smaller investors. Were I an existing investor or angel, the definitives adding a threshold would feel like a retrade of the term sheet.

Especially if the intent is to help unfamiliar founders & angels understand what's a "clean" or fair deal, I'd put in a vote that a v2 of this term sheet would clarify the applicability of rights to smaller investors, maybe with some "batteries included" guidance on that point.
