Tourna Black Zone 17 vs Tourna Big Hitter Black 7 17.

Other than the obvious difference of TBHB7 being a shaped string how do these strings compare? It looks like TBHBZ is much softer with a little less tension maintenance. Would you string these strings at the same tension full bed? I’m playing TBHB7 at 48lbs in the Wilson 6.1 18x20 and getting ready to string up some TBHBZ this morning. With it being much softer wondering if I should stay the same tension or go up to around 50.

Having experimented with both, TBHB7 and TBHBZ are close in stiffness. As with some changes, I would recommend changing just the single variable - the string only. TBHBZ is relatively slippery.

Thanks, will go with the same tension. Thought it was strange that the chart was saying there was such a big difference in stiffness between the two.

To me, Zone plays about what its stiffness rating would suggest.

Its the BHB7 that seems softer compared to its stats. Hope that helps.
Just strung one of my 18x20’s at 47 with Zone and the other two frames are strung at 48 with BHB7. Will be interesting to compare this weekend.

Update: the BHBZ plays a little more muted and less power than the BHB7. BHB7 generates a bit more spin as well but feel like I have more control with the BHBZ especially on the serve. Great string and will go through a reel next several months. Hard to beat $4.00 a frame as well as this string plays.

Tourna reels are a great deal. Some companies offer a small discount in reels. Tourna offers a great discount. Tourna Big Hitter Silver... $4.00 a set from reel. Along with others as stated above.. If you string for others.. that is all profit .. :)

I also found both to play at the expected stiffness, but a bigger difference for me was that Zone is coated: it played slicker than snot for a few hours and was unremarkable after that.

Maybe more importantly for differences, I got the distinct (but maybe mistaken) impression back when Zone was released that it was being marketed as a cross for hybrid poly string beds. I used it that way, to cross BHB7 (38 lb in a FIscher MPro 105) and got, by far, the best spin I have ever experienced with any string bed. The downsides were that (1) I had it for only one day (a full teaching day, so about six hours, hitting hard for less than half that) before it reverted to standard shaped-poly spin on Day Two, and (2) I found the combination noticeably less pleasant-feeling at contact than a full bed of BHB7 — or any other soft poly.

What sticks in my mind about that afternoon is how lucky it was that the combination worked. TWU's friction coefficient numbers apply only to a full bed of whatever string it is; they tell us nothing about how a string will slide against a different string. You'd think two strings from the same company with low friction numbers would always slide well against each other, but I've been hilariously wrong making that assumption, so BHB7/BZ was a memorable discovery for me.

For fun I put tourna zone in as a cross in one of my frames this weekend, started that one out in warmups, but before my match even started tonight, I was back to my isospeed cream cross frame!

I guess I can't handle more then 20% poly.

Anyone use Black Zone as a cross for Natural Gut?
Yes I have. It's a nice setup. Currently playing Gut/Poly Tour Fire but bought a pack of Black Zone again to compare directly to PTF.
Happy with PTF but looking to save some money.

It's not as spin friendly as say Gut/Revolve but enough spin and I feel more control than Revolve. Hoping I like it as much as PTF as the price is good.
