When talking about Tacks, you need to specify if you're talking about the original revival line, (I think around 2012) or the current/previous generation Super Tacks line. They are very different fits.
To answer your question, no, Bauer skates will not give you more forward flex. In fact, at equal price points CCM skates generally are a bit softer than Bauer.
If the Tacks skate fits you well, your best bet is to either learn to skate without the top eyelet, (will take a few ice times to get used to it) or adjust your lacing. You can also install lace locks to help with modified lacing.
