@nosmoking The octopus is hiding a few arms as its secret weapon =P 25 and 30mm are both great setups and really come down to the users preference as some prefer the smaller dab surface area over the larger format. But they will both work great regardless of the selection. The 25mm is a bit easier to find a cap for as pretty much anything large or small will fit it perfectly. The 30 takes a little more investigation to make sure the caps will fit and not sit inside or sort of inside (Depending on how much off they are from the inner diameter of the banger) NEglass has a section just for 30mm caps and personally I would recommend looking for a more restrictive cap if you are going with the 30mm. For me personally, I like more restriction on the 30 over the 25. But again, I think this is just a preference thing for the most part =)
