I bouth some DR Highbeams .40-.100. I just wanna ask how long do they last before they start to give out. Ive been using Dadarrio nickel XL's, I had an odd set, I had a .105 E and the rest were from a .40-100. And my E after a whil of playing would start to get dull anmd basically turn into a flatwound. I would clean itand after a while of playing it would go back. WIll i have the same problem with the CR's are am I going to have to do A cleaning eveytime a start and finish playing?
