Got these after searching and realising no other brand carries gauges this thick. Tuning down to G och F# on a lon scale bass (34-35") bass makes for a mess with a .135-string, but with these babies you're home! After adjusting the nut (widening, don't make the groves more shallow!) and the bridge on an Ibanez SR I could only be amazed at the clarity of wich the lowest notes rang. Add to that great sustain, and after punishing them for months they still haver a lot of string sound left in them, so they seem very durable if you only wipe them down the finished playing. The lowest one we're however a pain getting all stretched out (same for several pairs) and getting it to stay in tune, a lot of elasticity in that one. Given that they are (as far as I was able to deduce) the only ones available in this gauge, the price is fair I suppose, but an alternative would be interesting to try, but untill then, these babies rock!
