I would not recommend bluff raising a limper with trash hands in the Foxwoods $75-$150 game, simply because the immediate odds they get makes it correct to call your raise. It's a high ante game ($15 ante, $25 forced bet) so after you raise the pot will be (assuming full game):

(ante = 8 * $15 = $120) + (bring in and limper = 2 * $25 = $50) + (your raise = $75) = $245

Assuming the bring-in folds that means the limper gets $245:$50 odds, almost 5-1 and is correct to call. And they usually will, meaning you will frequently get yourself in trouble bluff raising with just a high card. You'll need something a little stronger than just a high card.

Now with hands like AKT, or a high 3-flush it's OK, since most of the time you'll be at least close to even money to win, so with the dead money it's actually correct to isolate a limper especially if you have some control over the player.

There are some players who are soft and a lot of times like to see 4th and 5th and will give it up immediately on 5th if they don't improve regardless of what you catch. Against them you can raise more freely, but against most I would not recommend it.
