I have arthiritic thumbs. I find that the weight, balance and overall "playability" of an instrument is quite an individual thing literally "in my hands".
One factor may have to do with placement of the thumbstraps and an instrument's center of gravity. Another variable may be my expectations from an instrument and how I "attack" to get the sound I want. I've found wrist straps anywhere from "in the way" to essential depending on the instrument.
There doesn't seem to be a hard and fast rule; one treble works better for me with wrist staps; one doesn't. I was having a devil of a time with an Edeo t/t
until I installed w. straps and now it's a favorite. Surprisingly, a baritone treble plays quite well (primarilly on both knees) without engaging the w. straps.
I think it can be worthwhile to review the Goran Rahm posts on ergonometrics or visit his current You Tube offerings.
When I began playing anglo Paul Groff gave me some great cautionary advice that it could take time (years in my case) to develope the support musculature in playing Irish Trad. I suppose it is a combination of evolving technique and body accomodation.
So I guess I'm saying you'll probably need to experiment and find your best way to get along with your new baritone.
Good luck! Sounds like a great, new adventure.
