NY Cheesecake is such a nice flavour. I tried something similar when I first started mixing, think it was 10% NYC & 8% sweet strawberry. Thought the NYC was kinda sickly at such a high % though and reduced it to 5% and it's lost most of that sickliness. Ended up with:
NYC 5%
Sweet Strawberry 2.5%
Strawberry Ripe 3.5%
Feel its lacking the biscuity base from a cheesecake though, thinking of trying some FA Cookie with it next time.
