I use GHS Boomers with a 10.5 E string. I like to bend a lot and the sound and feel of the E string are the most important characteristics I look for. I have tried many different brands and sizes of strings. I like 10s for their feel and 11s for their sound but find the 10.5s the best compromise. Lighter strings bend more easily but heavier stings have better tone. I suggest players try different strings till they find the best compromise that fits their playing style. The 10.5s work very well for playing Blues with a lot of Albert King style bending.
