Low limit ante/bring in structures stars vs full tilt

[Noir_Desir]

I have played HORSE and Stud 2/4 and 3/6 on both sites and there are quite big differences between the structures.

FT:
2/4 ante $0.4,$0.5 bring in
3/6 ante $0.5,$1 bring in

Stars:
2/4 ante $0.25, $1 bring in
3/6 ante $0.25, $1 bring in

Which structure do you like better and which adjustments should one make? The difference between money in the pot on the 2/4 level is not that big, but the bringin gets worse odds on defending on FT. So should one steal more?

I think the 3/6 structure on Stars is pretty awful and kills action. I thought about emailing them to increase antes to $0.5 . What do you think?
