Imeo, few questions please:
1- If i have Ithaka short mode (without upper body) all Ithaka, except mouthpiece of Odysseus, is there a problem in opening the mouthpiece all the way? (since size of engraved + clear = 15mm, versus 17mm for ody tank)
2- The telescopic mouthpiece when it is in smallest size, is it the same size of odysseus mouthpiece? Then do we have a problem like in the first question? (a solution can be to keep the o-rings visible on clear window so i can get additional 2mm)
3- You said telescopic mouthpiece can be used in Ody full mode. However i don't think it is possible, since if it was we could have 4 upper bodies on Ithaka (Ody full mode is around 42 mm of tanks, vs Ithaka with 2 additional upper bodies = 9 + 6 + 7 + 7 + 7 = 36mm in tanks)
