The picks are pretty good - I mean, I dont really notice a difference between these and the regular sharps aside from maybe a bit of the "tortex" like spray they have on them. Yes it gives you grip but I found no problems with the original formula either. Not really a big surprise, youre just paying extra for the logo & tin here.
Very good pics, I like the tip to be a bit sharper than the standard Tortex pic which this is. One thing to watch out fr with the Ultex is that the pic is stiffer than Tortex so you may want to go a bit lighter than you would do if you use Tortex pics.
