Double Bass New! Pirastro Perpetual Double Bass strings

Anyone have an idea how the tension on the Perpetuals compares to Flex Deluxes or 4/4 Spiro Mittels or Weichs?
Both manufacturers Pirastro and Thomastik have the tension specs covered on their web pages for each strings. And that tension is the "technically measured quality" of course.
On my bass the perceived tension of these sets matches very well with the measured specs. @DoubleMIDI has very useful Exel file where you can compare all these strings tensions calculated on a same mensur length.
 
Yeah Troy, funny how perception is: I did think the G made things better (on my bass, hands, sound etc) and I DID think it made spires a whole lot better. The D stark is full of tone which I really like all the way up it has a kind of voice that has more personality and individuality then any other D i've tried (I have not tried on my bass a D Oliv which I would love to at some point but after my recent experience with the winding I think Im sticking to the Starks for a while)

To be clear, I liked the Stark G. I haven't tried the Stark D, but I suspect that I would like it as well. I just don't think the regular perp set needed it and it feels better balanced to me as originally shipped.

If they keep going and make a balanced 4 string set based on the stark D and G, I would be interested, but I'm back to the original perp set now and considering putting the Spirocores back on, mostly because my perp set is too old at this point and though the Spirocores are likely older, I suspect they age better. I haven't bought a set of strings in a few years and I'm hemorrhaging discretionary income in a different direction at the moment.

Well, now you've did it...your praises made me purchasing a D Stark too....;):p there are a few delivery problems right now, but I'm very curious about this string after my experiences with the G Stark...:p

I ordered a perpetual stark G to go with my reg. perpetual EAD. My luthier is a bit busy at the moment, but wondering if anyone has had to sand/file the bridge and nut when they replaced the reg. perpetual G with the Stark? And if you did so yourself vs. taking to luthier

no. it MIGHT be as thick as an evah regular g which doesn’t require filing. You’ll be fine

I just changed the string and it worked perfectly...:) the tension is a little bit higher, but I think that is hardly noticeable when playing. And as already said it works and sound so great, that I ordered a Stark D too ...;)

So far the Stark D and G are winners for me. I’m pairing them with 3/4 Spiro Weichs. Here’s a question for all of you that have used the Stark G and have experience with the Evah Weich G. How would you compare the the perceived tension between the two? Thanks!

It's been a while since I've used Evah Weich, but I would say that the Perpetual stark G was thicker with slightly less tension.

I love round core strings on any instrument, but that's what I think is really special about the Perpetuals for doublebass. There is a stiffness and sharpness to Spirocore Weich that I don't prefer. I may put an S42 Mittel G on there at some point, but my issue last night is that my string height is too much after installing the Yamahiko and that can be fixed with a trip to the luthier.
