 I believe that you mean Maniton (not Manitou) water bottles and while 
he did have then break from time to time he attributed it to a a cascading 
effect. The bottles (is placed in series) were able to withstand an 
EMF of 30,000 safely and stated that he thought the glass was 
excellent. (Colorado Springs notes by Nolit page 120.) As far as them 
giving way, I want to know how many TC builders are putting thier 
coils under the kind of stress Tesla did? I don't think that this is 
an issue unless you are a very serious TC Builder. Most of what I 
have seen posted on this site are neon sign transformer Tesla Coils 
with emf in the 10 to 15KV range. 
As far as "farting" around with the water level he did this on 
numerous occasions though I concede that wiring swaps were used
mostly (much easier to do!) but you will also see different 
capacitance values used due to differing bottle draft.
As far as loosing water due to evaporation that was not the case 
since he plugged the top with parafin oil (also page 120).

My point was that there is no need to downplay bottle caps for the 
novice. Not everyone has either the time or resources to do it by more 
"efficient" means.
