The swings in 10/20 are much greater than 5/10. There is more aggresive betting and semi-bluffing going on. Less limping on 3rd. More completions on third. A tougher game in general, although there are times when it is riper to play. If you become familliar with your opponents, you will know when that riper time is.

But beware, that the swings can be great at time and you might be comfortable with a $1,000-$1500 swing downward. It can be a profitable game, but if you're not comfortable with wider swings, it might not be for you. But if you are looking for a more interesting and exciting game, then you will enjoy it, especially if you can win at it.

Good luck.
