I'm mostly worried about the cycle of repeated over correction and testing

I like long barrels. If anything, I will consider sportsterizing,
Tapering the barrel, slenderizing the stock, and removing the extra mechanicals from the extendible cocking arm etc. Just lighten up!
But first, I just want to shoot it a bit and see if it's anything worth having.
I must admit that getting more enjoyment than I'm having with the TS-45's is going to be a real challenge!

Those little side cockers are back porch riot!
