Which ICS openings made you switch to them from the rep you were playing before?

A long topic title to generally ask the similarly long question:

If you had an opening rep before starting on the ICS one, which of the ICS parts made you switch because they were better? Perhaps you didn;t switch to the entire ICS rep, but just cherry-picked some great stuff against the Philidor or the London etc.

Basically, I am looking for a highlights of the openings course that might be worth me looking at.

Over time I have purchased all the offerings of ICS as they occasionally are on sale. I am currently using the ICS opening suggestions for Daily Games on chess.com. I seem to have ok results with the Scandinavian defense but at my level players use all kinds of different openings otherwise but seem to use 1 e4 the most. Developing a repertoire is an evolving process. The ICS suggested openings change in the latter few lessons.

LOL here's some necroposting. But I switched from Sicilian hyperaccel. Dragon to Scandinavian. Reason: far less study. I want t focus on strategy lessons first.
Disadantage: I've chosen for the ...Qd6 variation and then fairly soon ...b4. But I feel it's kinda drawish.

None. I didn't have a repertoire before and I still suck at openings.

Oh yeah, me too. I I just know the little bit. The most important thing I've learned about openings is that it's a struggle. If you're struggling for center and space, then it's not you, it's normal.

I know enough to get by, but sometimes I still end up in almost lost positions because I screw up in the opening. Interestingly though, many opponents do the same. Especially if they fall into opening traps.

I am slowly building a repertoire now, but I'm not using the ones from ICS.
