Tell us tell us what frame
As much as I'm into pfs now the cast targas at proshot look very tempting.
I got 2 cast targas, they are great. I am thinking of am edc ttf frame, more pocket friendly, not sure what yet :-(
You need professional help . . . but a new slingshot is cheaper ; )
For an EDC ttf my go to is the wasp uniphoxx nothing fancy but does the job and with the cost no worries if you lose, damage or give it to someone else to try.
