Gotchya. Probably longer lasting at the expense of some grip. If I ever wear out the Pirellis will try some Contis.Trail casing would be alright as I know where you ride. The only problem with trail casing in the more aggressive group is it only comes in the entry level endurance rubber.
The latest set of Kryptotals I ordered, I got an enduro front with a DH rear. The rear definitely takes a bigger beating as it doesn't follow the path of the front and rubs shit on the way down/up, has more weight over it and does the squirm/schralp on corners, bringing the casing in to play.
