Hey! I have a knock off Cobra (60 mm total length) and knock off HT5 (80mm total length, Nano). The HT5 fits quite OK actually. Cobra also fits, but just not as good for some reason. Now that my girlfriend is really on board we would like to purchase a CK. Yesterday I was at the point to order the Small version, but if I am not mistaken the Standard is also already smaller than the HT Nano, which is OK, which is why I am also considering the small. How do the Standard and Small CK's compare to preferably the HT or the Cobras? Many, many thanks!
