I think I have tried every kind of mandolin string there is out there. I like to play bluegrass and old timey and also play in a church band. Something about the bluegrass folk made me feel lesser of a man because I didn't have phosphorus bronze strings like J-74 or J-75's . I had those strings many many times but my finger acid would eat them up in no time and they would be dead sounding with scum under them in days. The first time I received my expensive set of T-1's (wish they were cheaper)I was immediately impressed with the feel right out of the package. They feel so good on the fingers...they sound great..no finger noise....and they last forever....They are a great string. If you have never tried them and the price is whats keeping you from getting them...bite the bullet once and go for it you'll love them. I give the quality a 5 star ..but I'm gonna give them a 4 star because of the price. I have to say though JustStrings.com is the cheapest place I found to buy them.
