Yeah, I just prefer the way a tipped grenadine hangs. I'm not big on the transparency of the untipped end either. I like the ones I have and will still wear them but don't think I'll get more.
Untipped non-grenadines I'm fine with; all my Vandas are untipped and I wear them a lot.
Funny, I think I'm the exact opposite, well, at least with the wool challis and grenadines. I could be swayed either way on the others I suppose.
