There are no sites, as far as I know, where there is "very stiff" competition at $25 NL. Possibly Ultimate Bet used to be somewhat tight. The very worst players, IMO, are at: Tribeca network (victor chandler/doyles room/others) and Bodog.

Some players at BTP have said that Tribeca and Bodog are high-variance sites, where you may have a high win rate but it will come with a lot of ups and downs. The players are so danged bad and they love to get all-in with junk. Sometimes they will suckout and beat you. However, I haven't had these problems.

Both sites have bonuses that clear just fine at both $25 NL and $50 NL. They have provided me with my highest winrates overall at $50 NL. I recommend them.

If you want more advice from other people, there are a number of threads on this, mostly in the "bankroll management" and "poker rooms" sections of the site. Try searching for them....

I could've SWORN I posted a reply to this exact post already But anyway, k3nt is on the money about the Tribeca network - i'd also recommend taking a look at though and look at the "Whoring 101" link, it has some great advice for newcomers into the bonuswhoring world.

Btw, It's great that you're looking to add bonuses to your poker life and I think bonuses are an excellent way to pad your bankroll and help you get through tough times of variance - This past month i've made twice as much through bonuses as i've made through actual poker winnings (NL50 and NL100), so when you're moving up to a new level even if you're a break even player or slightly losing, your bankroll will still grow and you can take the time you need to work on your game without having to worry about your financial situation
