FYI I have been playing £25NL since mid 2005 - I only played $25 when I couldn't get on any £25 tables. Small difference but a genuine one I think.
Here's a thing. One of the first times I played $100NL my gf noticed and got concerned/annoyed because up till then I'd always been able to tell her I played at the lowest level (sorta). But once it got to $100 she thought that was Big Bucks (she's poor as a church mouse so I sympathise) and I guess I have a different version of the same concerns.
