I thought his main concern with the one he currently has was the high price. I assumed he wanted a back up, but didn't really want to dump the $$$ on another one. So I took that to mean the OP was asking what he should do- hence the direction of at the very least get the same style. I shoot a nice finger/wrist rocket at the cost of $90. My back up?
A $15 one from Cabelas. Neither changes my shot placement. Both are the same style of release
I could've been wrong in assuming this was your original thought process in your asking?
If at all possible, Yes get the exact same and set it up the same, if its not possible, get 2 like styles, set up, with same anchor point and practice with both as stated.
