I think 100% equities makes sense with your age.

I think you should go for a lump sum deposit. A 1994 paper - Lump-Sum Investing Versus Dollar-Averaging (https://papers.ssrn.com/sol3/papers.cfm?abstract_id=820004) - found that investing in a single lump sum can be expected to provide a higher return. Risk-averse investors who prefer dollar-averaging can accomplish the aim of risk reduction more effectively by lowering the fraction of funds invested in the risky asset and investing them all at once.

​

In other words, invest in one lump-sum but if you want to balance risk invest some of that money in bonds.
