I assume you want to use these tapes on more valuable/important stuff.
They may be better than self adhesive tapes (but the worst are probably worse than the best self adhesive!), but should not be used for the very best, for the very best you either need to use no adhesive at all or the best there is, and the best there is, you make yourself and the same applies to the hinges.
I don’t know why but there seems to be huge reluctance amongst uk framers to learn the art (and it is one) of cooking fresh paste and wet-tearing Japanese tissues, from a stock of varying weights and shades.
The same principles regarding moisture will apply though - all you need do is learn how wet your tape should be - with paste it is generally left until not shiny.
You have no control over the consistency of water but you can cook paste to something you can practically roll in to a hall if you like - and then thin it with water if required.
Tapes do not have feathered edges - some may be “deckled” but not feathered but most are not and even if you wet tear the end (most framers just don’t do that) you cannot do the same to the sides.
You can also pay less for the best than you can for some gummed tapes like hayaku and once adept it is every bit as convenient as you can pre-tear strips in advance - oh and also any width you like!
