I use the D'Addario J80 Octave mandolin strings. Phosphor-Bronze, loop end, gauges 12, 22, 32, 46. Heavy for most, but I like the fat tone on the G. Also you buy one set and get 8 strings. Makes my Mastertone big and beefy when you need to be heard.
I've also been using the Newtone Phosphor Bronze with 18w, 28w and 38w, but with 11 for the E for my Epi Rec A 19-fret and find them just about right. I like 'em. I've also tried the same in nickel wound, but I think the PB has a "warmer" sound. I also have a 17-fret TB and find these strings a bit light -- I'd like to try the D'Addario J80s suggested by Skavaka.
Hi Dick,I use the same make but buy them as singles from Eagle Music on line.
I keep with a 9 on the E as you say it gets hard work any higher.
9, 18 F/Bronze 28. and 38 but on some banjos up the third and fourth to 30.40
