Fine Swine and Bovine will be an excellent choice Sparky.
If you check at the market, you might find Tony's marinades with a injector taped to the bottle. Good way to have one on hand. The next time I order some Cajun Injector marinades they always toss in a freebie injector (they work purdy good), I will send you a couple...hang in there and good luck on the briskie...injecting is not a deal maker by any means....sometimes they come out just fine without injecting and sometime you wish ya did.............
