If you are keeping the Pig, a FS of similar ilk is a waste of cash. Get the best spread you can.
If its just one bike, then a 135/140 FS with good pedalling manners will cover everything.
If you keep the Pig, get a 160 for those Alp trips/Fun days. My main bike is a Titus FTMc with a 140 Talas. Its uberlight, and can handle most stuff. My second bike was a C456, which was really just a HT version of the same bike, so I’ve parted it out and I am building a Heckler with Marz55’s.
If I was buying a new 160 FS, the Canyon Strive would definately be on the list.
