Ok, so in my head I want the biggest table possible in terms of proportions. F colour VVs2 minimum spec, obviously want best cut possible for light return otherwise paying for the high colour and clarity is pointless.
I found one here but igi certificate dosent give an indication of light performance unless its ags.
How big are the first two you posted (that are already in settings) Lxw?
Not that impressed with the 1.55 or the 1.54 (very mushy under the table).
The 1.52 looks to be the best cut of the linked stones. Yes, it does have somewhat of a princess-ey look on the pavilion side
so, if that's not a look you like you probably need to keep looking.
Edit...you may need to lower some of your specs to open up your options a little more
