Mono again or Gruv Gear?

[woodster]

I’m currently looking at replacing my battered old Mono M80 double bag and I’m wondering if it’s still the best or whether something like the Gruv Gear Kapsule Duo is a decent alternative. 
 

The M80 has served me well but I like the wheels on the Kapsule and although Mono are putting detachable wheels on one of their models, they are reluctant to tell me whether this will extend to the M80 range. 
 

Anyone got a Kapsule they can tell me about?
