Your opinion on Leather Specialties/Yamaha strap

[MStarke]

I don't really have any pain or larger issue holding my bass trombones without an additional grip support. However I realized that flexibility in the fingers sometimes gets lost when holding it for a while, sometimes with a light cramping feel in the fingers so I cannot really use the triggers perfectly.

I don't want to put any more invasive/fixed grip on and don't think I really need much support. I also kind of prefer not having too much extra control on the hands and being able to move them kind of freely.
So today I tried again the Leather Specialties strap that I have lying around for many years now.
That seems to be just enough extra support to relieve the hand/fingers a bit.

What's your experience?
I just have a little worry that it puts stress on the mouthpiece receiver/upper inner slide area and might over the long term affect alignment. Probably that's unrealistic. Any experience/opinion, especially from the brass techs here?

I use the Osmun one on bass. It's awesome. No issues with stressing the slide.

It makes using both triggers so much easier.

[Burgerbob]

Used mine for years, no problems with any of those slides. The leverage is not in favor of the strap pulling the slide out of alignment.

[MStarke]

Thank you both! I thought so, but wanted to double-check.

Also these straps are comparably cheap so that it's okay to have one or two extras, e.g. One in the case and one on the stand.

I have used one 100% of the time for almost 9 years. No slide problems, and it keeps the hand and wrist problems I was having from coming back.

[LeTromboniste]

Yup, used one on modern bass, and have been using one on bass sackbut for several years. I actually don't see a reason not to use one.

I’ve used the LS, Clebsch and Yam straps. All worked well. The Yam was very inexpensive.

The last few years I’ve used a Get-A-Grip and a Calderpips grip, which I prefer to the straps.

The straps are especially good if you’re prone to leaving things behind at rehearsals.

For the Yamaha strap, I'm assuming you're looking at the black one that hooks around the mouthpiece/receiver (Yamaha YAC1535P). There is another strap, the Yamaha TBHS2, that's pretty great. It's a different design. So far, I've only been able to find them for sale from Japanese sources. There are a bunch of sellers on eBay. It's more expensive, but I've bought 3 of them. I tried Leather Specialties and the other Yamaha. These are superior IMO. YMMV.

I have been using the Leather Specialties strap on my basses for the last weeks now.
It definitely relieved the fingers and immediately improved using the valves.

I don't really know why I didn't do this earlier...
