Which rubber? (next step)

(Using on a provincial 301 blade)
Option 1. Switch to a hybrid. Tried K3 on my coach's pro 301 and it felt nice, however when I played k3 I noticed that it died very quickly. Any more durable alternatives?
Option 2. Speed up, potentially to Hammond Z2. I don't think I need a faster rubber at this stage though.

I want this rubber to be similar or better than c-1 in aspects such as fast driving, counters, open ups, and especially blocking. Blocks on C-1 aren't as 'penetrating' as I'd like them to be. Thoughts?
