Fortunately we only have to upgrade to 40. And then, upgrading strong teeth is dumb. That takes off a lot of necessary tears.
I'll stop upgrading at 40 too, 1 more Lil' Scorcher................. Before Dried Tears most people stopped upgrading traps at 26, because upgrading up to 30 was useless..............
But the ones that upgraded to 30 anyways, had an advantage (32 * 24hrs) when the cap increased to 46 and so will the ones that upgrade their traps to 46.
Basically it's an advantage of 48 * 24hrs
