Replying to Beginner looking to get into backcountry

soo i'm looking to get into backcountry a little bit. but i live in NH so i'm not looking to get super into it and spend a ton of money. I was thinking about getting a set of alpine trekkers to use on my bacons that are mounted with px15s. most of my tours will be extremely short so i really think this is the best option. Anyone have any suggestions on skins? I found a pair of used skins that are 90mm will these work on my bacons that are 115 underfoot? what about kicker skins? like a said my tours will be short and relatively low angle
