string brands

Hello, I recently had come across Newtone strings while searching for Stringjoy/Kalium alternatives and noticed they offer every gauge. I thought it would be nice to finally get odd and even numbered gauges in a set especially when other brands don't offer 82,83,84,etc Does anyone have...

Id like to keep my higher string at a 10 13 and 17 and wouldn't wanna go any higher for a 64 for the 7th. I've thought about trying a 10-46 set for the 1st 6 but something tells me that'd be a little too loose, id like to stray away from the 10-52 set I've been using for years. What do you guys...

I want to buy a six string bass, but my band plays 8 string guitars and i want to be an octave lower and tune my bass to E B E A D G. What gauge should i use for my lower strings, and where can i find strings that size because my local guitar center is horrible for bass...?

a lot of brands like Ernie Ball and DR (my 2 fav.) dont even fit on a 27" scale (with a reverse headstock, so its only the lowest string that doesn't reach) What brands are long enough for a 27" scale so i dont have to keep wasting money trying different brands?
