Alexi Laiho DR Commercial

I ordered a set of DR Strings, 11-50, to see what they're like. I've only ever used Ernie Balls so lets see what the hype is about!

And I've never liked 11's in D, but atm, I'm feeling my 10's are a little weak, but that might be because my action is super low and the strings are pretty worn.
I hope you mean the Tite-fit 11-50 strings. The Dimebag signatures are a total waste of money, they sound amazing for about 2 days and then they wear out and sound like utter crap.
Personally I use the DR Jeff Healey signature strings 10-56, they're my favorite string-set so far.
 
I've used D'Addario strings for forever, and recently decided to try out DR 10-52 Tite-fits. So far, I really like them a lot in all areas.
