Helicore Hybrid Heavy Tension

[threetone]

I'm looking into D'addario Helicore Hybrid 'heavy tension' strings for my carved flatback.

So far the increase in tension from Spiro Weich to Spiro Mittel made a big big difference in the overal sound, volume and feel of my bass.

Does anyone have experience with Helicore Hybrids high tension strings compared to Spiro Mittels?
Thanks
