I think you just said it. If you want it smoother on the palm, you'd probably be happier with any number of flat mainspring housings...from completely smooth to relatively rough checkering. I prefer the rougher 20-lpi checkering...but companies like Ed Brown make a lot in between with their "Chainlink" and "Snakeskin" patterns. etc.
I'm fine with standard A1 configs with short triggers and arched housings, but I prefer a longer trigger and flat, aggressive checkered housings. I wasted a lot of money on parts figuring that out. But that's only me
They also make a wedge-shaped housing that you might like, but I haven't tried one.
