I have found of all the tips I've tried, 'Asian' tips which are ultra thin, blend easier than anything. Like butter as someone else has said.
Very little effort to blend these.
I've only tried a few 'clear' aka 'glass' tips (four different brands) and found that they are too hard, and tend to be brittle and more prone to breakage than regular tips or sculpts.
IF you can, I would sculpt.
I've only recently been learning how and love it already, although I'm not the greatest at it.
I can see all the benefits... and my boxes and boxes and boxes of my wide variety of tips have been collecting dust for 2mths now.
What tip to use with the glitter would depend on how dense you want the glitter to be and if what the end result is that you want
Do you want it to be so dense, you can't see through it? Then the tip doesn't matter.
Do you want it just a bit and want a clear tip?
Do you want the "natural" nail to show through the glitter?
It really depends on what you want. There is no right or wrong way.
