Have you considered using the Gator Tooth clamps for that usecase ?
I’m not saying there would not be value in long Tiger Claw clamps, just mentioning that the Gator Tooth are longer, so what can work is using a pair of Gator Tooth on one side and Tiger Claw on the other side, with the stock positioned such that it is closer to a row/column of wasteboard holes on the side with the Tiger Claws, while the longer Gator Tooth make up for the largest distance to the nearest holes on their side.
