Those are the same Tortex I use. I have a pack of red Jazz 3's I haven't touched cause I'm a creature of habit. It feels weird holding something so small lol. I like the tortex a lot when playing like punk rock.. but might try and wean myself into Jazz for more precise picking styles. Trem picking does feel kinda out of control with the tortex lol.
I know exactly what you mean, and I almost gave up! It took about 2 weeks of daily playing to stop 'losing' the jazz3 in my fingers - but now it feels like the complete opposite and I can't imagine how I fit ALL of the tortex one in my hand hehe
