Biggest hurdle for most people tho isn't necessarily the more frequent pins, but the number of sites eod pinning requires since most will be Virgin muscles. If you're concerned about the pip and such with that, then what I usually tell folks is to run a long ester base and throw the prop in as a taper. And to adapt to the new sites, commit to a 6 site rotation with the long ester using glutes, quads, and delts. One CC each and a different site with each pin. By the time you get to your prop taper, they're primed. The initial pip, if any will be from the new oil and solvent ratio.
