Pablo's post about string tension and that ideal set got me to thinking... What WOULD Be a good set for a 7 string? I noticed even with the baritone length, my A COULD be a bit tighter...here's what i came up with for a set starting with a 10 top string, and going down:

len 27.0" == 27.0"

D .010" PL == 14.43# ( 0.0040gm/cm 293.7hz )
A, .014" PL == 15.87# ( 0.0078gm/cm 220.0hz )
F, .019" PB == 16.63# ( 0.0129gm/cm 174.6hz )
C, .026" PB == 17.63# ( 0.0244gm/cm 130.8hz )
G,, .035" PB == 18.4# ( 0.0453gm/cm 98.0hz )
D,, .048" PB == 19.22# ( 0.0843gm/cm 73.4hz )
A,,, .065" PB == 19.22# ( 0.1502gm/cm 55.0hz )

total == 121.4#

Vs a set of 9's in standard tuning:

len 27.0"

E .009" PL == 14.72#
B, .012" PL == 14.69#
G, .017" PB == 15.82#
D, .024" PB == 19.02#
A,, .032" PB == 19.21#
E,, .042" PB == 18.84#
B,,, .054" PB == 17.02#

total == 119.33#

its on 2 lbs more tension on the whole. Thoughts? ideas?
Also, worth mention, a 10 set of lite top/heavy bottom D'Addarios on a standard 25.5" produces 128LBS of tension,.

Based on what i can find at just strings.com, i can assemble this set:

len 27.0"

D .010" PL == 14.43#
A, .014" PL == 15.87#
F, .018" PL == 16.53#
C, .026" PB == 17.63#
G,, .036" PB == 19.46#
D,, .049" PB == 20.01#
A,,, .068" PB == 20.77#

total == 124.7#

Also, there was some mention of equal tension on all strings.. that would look something like this:

len 27.0"

D .011" PL == 17.46#
A, .015" PL == 18.22#
F, .019" PL == 18.42#
C, .026" PB == 17.63#
G,, .034" PB == 17.33#
D,, .045" PB == 17.0#
A,,, .062" PB == 17.67#

total = == 123.72#

Thats the closest i could get to it. Dunno if its possible to assemble though

Are you doing the calculations based on the D'Addario string tension chart?? Bloody handy, that thing.
I got into the theory of balanced sets a while back, and then again when working on the fanned fret designs. It would be great to have balanced tension sets, and sets that progressively increase in tension from treble to bass. But selling them to the masses is another matter. I'd put money on a company like D'Addario having discussed and trialed them, but abandoning it as a marketing mistake.

I seem to have missed Pablo's thread somehow

Now this thread I like...way to go man I am impressed...its fun once you start calculating them tensions huh?
My set of 8.5's to 59's is now in the mail, coming from juststrings, I can't wait.

Here they are:

Optimum String Gauge?

and

String gauge for A tuning

[Metal Ken]

Yeah its interesting stuff. I Just changed my strings on the RG1077 2 days ago but next time it needs string changing im going to try the set i came up with.

Good for you...the way I figure it is, either I won't feel the difference or I will, either way it's the cost of a set of strings (I'm banking on feeling a difference though)
I've ordered a set of Optimums for my six string also, 10's to 49's from Zack(hell since it's his theory I feel terrible about not sending some business his way)

[Metal Ken]

I'd send him some business, cause its cheaper to buy from him than get them from just strings, i think, but he doesnt have 7 string baritone sets. and i know the 7th & 8th string on his baritone he just uses Bass strings, something obscene like a 90 and a 105.i dont need THAT big of a string.

More tweaking again.. This time for Schecter scale length:

len 26.5"

E4b .009" PL == 12.64#
A3# .013" PL == 14.8#
F3# .017" PL == 15.94#
D3b .024" PB == 16.33#
A2b .032" PB == 16.49#
E2b .044" PB == 17.64#
B1b .060" PB == 17.99#

Only one problem dude, you're using PB in those calculations. That implies you're using phosphor bronze strings. I think you meant to use NW, which is for nickel wound strings (or nickel plated steel techniclly), but the top three with PL are fine.

That being said, I'm interested in testing that Zach guy's optimal string tension theory. I think what I might try to do is buy a set of d'addario 9-42's and buy a different gauge for the high b, low e, and low b (the rest are fine). My calculations are below:
