When I started playing, I had a lot of trouble with the standard mid-size .72mm size pick. I initially got some .50mm ones but grew out of them fairly quickly. I've currently settled on a 1.5mm Dunlop Nylon Max Grip that lets me do what I want to do easy enough. You will find different picks respond differently, some are easier to hold than others.
It is going to be very specific to you, so given they're only about 60 cents or so each, get a large variety and see how you feel with them and then as you get better, what ones work with your style best.picks
So also to that, there's a fella on this site Jon Coursey, I believe he looks after things which is where i stole the above info from, you'll see it in this post attached here. Stupid I have to attach pics instead of the urls directly, but well.. *shrugs*
Forgot this stupid site eats my posts with URLs in it.
Ok, so if this works, I've attached a screenshot with the URL you're supposed to go to for rockstar recipe's helpdesk. You want to click on that 'new support ticket' button you should find on the right (not in my screenshot sorry) and pester them that way.
I got this information by searching for 'loyalty' which seemed to bring up your posts and ones for 'classic' membership.
