100% correct. Taking 10% away to remove downside risk of the remaining 90% is an absolute no-brainer, especially if it is a meaningful sum of money to you.

Indeed; I can't imagine a world where 11% higher gains makes a significant difference. Either that 11% is a large number in an absolute sense, in which case the 89% you retained is also VERY large; or it's not that big of an absolute number and doesn't matter that much anyway.
