VLS limitation, is there a solution within the Vanguard 'stable'?

Grogged

mrsG uses VWRL, VMID and VAGP for the core, VEVE and VHYL are used non core.
As most FTSE 100 companare global, VMID fills the UK brief (overall 10% UK in her case).
That said, it's so subjective, you could do it by replicating the underlying VLS funds, or stick to VWRL and your favoured (or not) bond ETF.
She prefers ETFs, but again, personal choice.
Personally I invest with ii as my SIPP is better suited to fixed fees and I do hold some of the above.
It really depends on what you're trying to achieve, personally I'd look at posts by @Alexland, @Thrugelmir, etc. who put it much better than I can!
