Solution vs solution comp sizing

To put simply I’m a 9.5/10 street shoe (depending on the brand) and was wondering what size to get the solution comps in. I have 42 in muirra VS and it’s near perfect fit but I’m wanting something super snug. For those with a 9.5 foot what size solutions do you rock?

I wear a 42/42.5 street shoe. In the Miura VS and Solution I wore 39. In the Solution comp, a 38.5.

With the softer heel, I found that the .5 size smaller results in a similar fit.
