Best iPoker site for rakeback?

[Ribsauce]

I did a search and found a thread about this, but it was just between Titan and Noble and it didn't seem to have an obvious answer.

I have already had an account on Betfred but no other iPoker site. Which one would you say is the best site to sign up for rakeback under? It looks like 35% is the max rakeback on all the iPoker sites. So I guess it is down to which site offers the best sign up bonus as well as reloads. I'd rather have quick clearing bonuses/reloads than ones that clear at like .25 cents an hour.

I mostly play 1/2 limit games (stud and HE) and NL50. I'll probably be moving up to 2/4 soon.

Any advice on which deal to take would be great!
